Can You Guess This TV Theme? #30 - Answer
Cantankerous news director Lou Grant, played by Ed Asner, gives her the job of producer of the 'Six O'Clock News', and Mary's cute quirkiness shines on from there.... Throughout the show's run, Mary develops wonderful relationships with her neighbors and co-workers, played by notables Cloris Leachman, Betty White, Georgia Engel, Ted Knight, Valerie Harper and Gavin MacLeod.
Did you know that 'The Mary Tyler Moore Show', has won a total of 29 Emmy Awards! Three of them being 'Outstanding Lead or Supporting Actress or Actor In A Comedy' awards won by Mary Tyler Moore, Ed Asner and Valerie Harper won three Emmy's each for lead and supporting actor and actress roles! The record of 29 Emmy Awards, held by 'The Mary Tyler Moore Show' for 25 years, was broken by 'Frasier' in 2002. 'Frasier' went on to win a total of 37 Emmy Awards!
I'm not sure I agree with 'Entertainment Weekly', but they list Mary Tyler Moore's throwing her hat up in the air in the show's introduction as #2 on their list of '100 Greatest Moments on Television'..... The #1 selection on their list was the assassination and funeral of John F. Kennedy. Mary tossing her hat in the air beat out:
- #9 - The Beatles first appearance on 'The Ed Sullivan Show',
- #17 - Edward R. Murrow interviews Sen. Joseph McCarthy,
- #36 - The Challenger explosion,
- #51 - The Dick Van Dyke Show - The first ottoman pratfall
- #71 - Bill Clinton playing saxophone on the 'Arsenio Hall Show', and
- #91 - The premiere of 'A Charlie Brown Christmas'
Perfect Strangers In Seattle?
By the way, did you know that Louie Anderson was cast for the role of Larry Appleton in the original pilot episode? It's true! Look!

Smart Guy Predicts The Super Bowl
In an episode of 'Smart Guy', the kids sneak into the television station to try to get their father's commercial for his roofing business to play during the prime time television hours. Little did they know that the commercial was going to play at halftime during the Super Bowl.... Ok, ok.... I'll get to the point.... Right before the commercial airs, the announcer reveals the halftime score of the Super Bowl:
Indianapolis - 3
Injured petrous internal carotid with proximal occlusion and clot from stab wound
Findings
Figure 1: Transaxial CT scan of the brain. Knife entering the superolateral aspect of the left nasal cavity.
Figure 2, Figure 3, and Figure 4: Transaxial CT scan of the brain. Knife traversing the midline.
Figure 5: Transaxial CT scan of the brain. Knife traverses the carotid canal with tip at the level of the internal auditory canal.
Figure 6: Transaxial CT scan of the brain. Postoperative pneumocephalus and posttraumatic infarction in the distribution of the right middle cerebral artery. Knife has been removed.
Figure 7: Angiogram of the right internal carotid artery in an oblique projection. Knife tip in close proximity to the right internal carotid artery with little flow seen intracranially. Spasm noted at the catheter tip in the internal carotid artery.
Figure 8: Angiogram of the right internal carotid artery in an AP projection. The knife traverses the midline with the knife tip in the right carotid canal.
Diagnosis: Injured petrous internal carotid with proximal occlusion and clot from stab wound
Gunshot wounds to the head have become the leading or second leading cause of head injury in many cities in the United States; penetrating head injuries can also be the result of stab wounds, and motor vehicle or occupational accidents. Knives are the most frequent weapon used in stab wounds to the cranium although bizarre craniocerebral-perforating injuries have been reported that were caused by nails, metal poles, ice picks, keys, pencils, crochet needles, chopsticks, and power drills. A mortality rate of 17% has been reported for cranial stab wounds, mostly related to vascular injury and massive intracerebral hematomas. The orbital surfaces and squamous portions of the temporal bones are the most frequently affected since these bones are thin and easily traversed. The morbidity from stab wounds to the squamous portion of the temporal bone is more severe due to the short distance to the deep brain stem and vascular structures.
CT scans are vital in the work up of patients with penetrating head injuries since they do show the extent of intracranial injury and fracture and rule out the presence of radiopaque foreign bodies. CT angiography is limited in the presence of metallic foreign bodies because of artifact; in these cases, conventional angiography is important in ruling out vascular injury and preoperative planning. Potential signs of vascular injury include transection, pseudoaneurysm and arterial-venous fistula. Occlusion is a sign, albeit a nonspecific sign, of an underlying vascular injury. In the case of a vascular injury, injection of the contralateral artery should be done to demonstrate crossfilling via collateral circulation in the circle of Willis prior to intervention. Cerebral vasospasm is another noteworthy finding since it can portend a poor outcome.
Patients with penetrating head injuries are often taken to surgery to remove hematomas which may be causing mass effect, to remove dead brain tissue to prevent further swelling and necrosis, and to control active bleeding. Metallic foreign bodies are often removed to prevent infection, the potential for fibroglial scarring with the ensuing development of epilepsy and intracranial migration. Knives should only be removed in the OR under direct visualization. Clot was noted in the proximal ICA below the presumed level of injury; coils were placed proximal to the clot to prevent migration of the clot. In the case of an obvious direct transection, coils may also be used to prevent exsanguinations when the knife is removed. Occlusion balloons can also be used.

Another Rescue On The Hudson
Since the plane crash, reporters and camera crews were kept away from the scene by the police and the FBI.... However, New Yorker David Hugh Martin, who has an apartment right above the Hudson River, positioned his camera to record the rescue of the plane.... Three days of rescue footage were clipped together to make an amazing time lapse video of crews trying to bring the plane out of the river. It's amazing to watch the plane struggle to stay afloat as huge chunks of ice barrage the rescue efforts....

Commercial Fit For The Super Bowl
One can really appreciate how WalMart was not only able to plug their status as the nation's low price leader, but also able to take a jab at people's inherent fear of clowns.... Well done WalMart. Well done....
Sialolithiasis with sialadenitis
Findings
The right parotid duct is markedly dilated. There is an obstructing calculus in the distal duct. There is inflammation in the right buccal space, the right masseter space, and in the right parotid gland. There is also a large non-obstructive stone in the right submandibular gland which was unchanged from a previous study.
Diagnosis: Sialolithiasis/sialadenitis
Discussion
Calculus disease is the most common benign condition to affect the salivary glands. The most common glands affected are the submandibular glands because secretions are more mucinous, viscous, and alkaline. Additionally, the duct drains uphill, making stasis more likely. Parotid glands are affected less frequently, and sublingual and minor salivary gland calculi are very uncommon. Patients generally have painful glands, worsened with chewing foods that precipitate salivation. Treatment is by administration of solutions that increase salivation to promote passing of the calculus. Transoral resection can be performed for calculi close to the ampulla. Resection of the gland may be used for proximal, glandular and/or recurrent sialoliths.
Radiologic overview
Imaging can be performed with plain radiographs, CT, and MRI. Most calculi are radio dense, but approximately 20% may not be visible on plain radiographs.
CT is more sensitive for detection of calcification than plain radiographs, and is also useful for detecting inflammatory masses and abscess formation.
In the case of non-radiopaque calculi, conventional sialography can be performed by cannulating the salivary duct and injecting contrast. The presence of a calculus is inferred by the presence of an intraluminal filling defect.
A new technique is MR sialography which is similar to MR cholangiopancreatography. The technique utilizes either a single shot fast spin echo T2-weighted sequence to image the duct alone, or a high resolution 3D fast spin echo T2 sequence to image the gland and duct.
Sialography is useful to demonstrate ductal strictures after passage of the stone, and in the evaluation of chronic sialadenitis from autoimmune causes.

Are You As LOST As I Am?
As a short warning, there is a commercial for Netflix at the end of the video, and I know how everybody hates commercials....
Neurocysticercosis (Calcified stage)
Findings
CT with contrast images showed a 7 mm calcified enhancing lesion within the posterior aspect of the left frontal lobe with a small amount of surrounding oedema. MRI images confirm the presence of a calcified ring enhancing lesion within the left posterior frontal lobe.
Differential diagnosis:
- Neurocysticercosis
- Tuberculoma
Diagnosis: Neurocysticercosis
Discussion
Cysticercosis is caused by larvae of the pork tape worm Taenia solium. Infestation occurs via the fecal-oral route. It is the most common parasitic infection involving the central nervous system in developing countries with 90% of patients present with seizures. Parenchymal cysticercosis is the most common type with lesions most commonly being peripherally distributed near the grey-white matter junction. The parasite goes through different stage of involution, each of which has different imaging features on CT and MRI.
These include the following:
- Vesical stage: CT shows hypodense non enhancing lesions. On MRI cysts follow CSF signal; T2 hyper intense scolex may be seen. No edema. Usually no enhancement.
- Colloidal stage: CT shows hypodense/isodense lesion with peripheral enhancement and perilesional edema. On MRI Cysts are hyperintense to CSF; surrounding edema, cyst wall enhances.
- Granular stage: CT shows nodular enhancing lesions. On MRI the cyst wall thickens and retracts, there is a decrease in edema, and there is nodular or ring enhancement.
- Calcified stage: When the parasite dies, nodular parenchymal calcifications are seen. These findings are best seen on CT.

Holy Kramer Entrances, Batman!
I was amazed by the amount of time he must have spent, and how much work he must have put into the project....
Well, here are two more videos by dedicated fans of their favorite television shows....
In the first video, YouTube user Apennyw put together every one of Robin's 'Holy Exclamation Quotes' from the first season of television's original 'Batman' show....

Klippel-Feil anomaly
Findings
There are multiple segmentation anomalies of the cervical spine, with fusion of C1-3.; left C6 hemivertebra.
Diagnosis: Klippel-Feil anomaly
Key points
Klippel-Feil anomaly refers to segmentation defects (congenital fusion) of the cervical spine.
Fusion of C2-3 and C5-6 most common
Frequently associated with Chiari malformation and syringohydromyelia.
Three categories:
- Group 1 = short, webbed neck, low hairline, complete lack of cervical segmentation
- Group 2 = isolated cervical segmentation defects
- Group 3 = segmentation defects affecting separate thoracic and/or lumbar level in addition of cervical involvement
Restricted motion at level of non-segmentation leads to accelerated disc degeneration.
50% of patients have at least partial dorsal splitting of the spinal cord. Defects in decussation of the corticospinal tracts can lead to "mirror movements" on physical exam.
Other CNS associations: occipital encephalocele, Dandy-Walker malformation, Duane syndrome, nasofrontal dermoid
Associated visceral anomalies: Sprengel deformity (20-30%, congenital elevation of the scapula, often with tethering omovertebral bone), cervical ribs, supranumary digits, tracheal and proximal bronchial stenosis, sickle sacrum, cleft palate, various renal anomalies.

The Late Shift
All before their friendship crumbled because Jay Leno and his manager used shady tactics to beat out David Letterman for the 'Tonight Show' host position after Johnny Carson had retired.... And when I say beat out, I mean, having an agent who bullies NBC executives and hiding in closets during executive meetings to gain an upper hand in negotiations.... Have you seen the movie 'The Late Shift'? It's about the battle for the 'Tonight Show' host gig.... Now we need 'The Late Shift 2' to cover NBC's latest debacle between Jay and Conan O'Brien....
Keep in mind, most of the videos include David Letterman asking Jay Leno a question, then Jay proceeding to talk for four to five minutes. But it was interesting to see their dynamic (and Jay 'Elvis' Leno) before the feud.... Click on the photo of Jay and Dave to see the videos....
Chuckles And The Chin - Team Conan or Team Leno?
The real losers are Conan's staff. All of the staff that had moved from New York to California with their families to work on 'The Tonight Show'.... They're getting a severance package, but now they're all unemployed in a horrible job market....
Oh, and NBC loses too.... Now they don't have Conan O'Brien and they're out $40 million.... That's one expensive mistake....

January Of Death
First Art Clokey, creator of Gumby, passes away on Friday, January 10, 2010 at the age of 88....
Then Donald Goerke, inventor of SpaghettiO's and Campbell's Chunky Soup line of products, passes away on Sunday, January 12, 2010 at the age of 83.... Did you know that during testing for the perfect spaghetti shape, they tested baseball, cowboy, spaceman and star shapes before they settled on the O's?
Then, Jan C. Gabriel, the man who coined the phrase 'Sunday! Sunday!!!! SUNDAY!!!!!', which is used in all those monster truck rally commercials, passed away at the age of 69....
After all these years, I never knew that Taco Bell was named after Mr. Bell.... I just thought 'Taco Bell' was a catchy name they came up with in a marketing meeting.... Did you know that he sold the Taco Bell chain to PepsiCo for in 1978 for $125 million in stock? Keep in mind that the price of the stock was around $26.00 a share in 1978.... Over the past 30 years, it's split three times after the price had risen to around $70.00 to $90.00 a share.... And now the price is around $60.00 a share.... How much money would he have if he had held on to that stock?
All. All money.
I Have A Dream
It amazes me to think that it was only 47 years ago that Martin Luther King Jr. delivered his 'I Have A Dream' speech. It's amazing that only 47 years ago, human beings had to fight for simple rights only because of the color of their skin.... If you've never heard or read Martin Luther King Jr.'s speech, take a bit and give it a gander.... It's amazingly powerful.... Oh, and look at that.... I have it right here for you.... Enjoy reading!
Five score years ago, a great American, in whose symbolic shadow we stand signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of captivity. But one hundred years later, we must face the tragic fact that the Negro is still not free.
One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languishing in the corners of American society and finds himself an exile in his own land.
So we have come here today to dramatize an appalling condition. In a sense we have come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir.
This note was a promise that all men would be guaranteed the inalienable rights of life, liberty, and the pursuit of happiness. It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check which has come back marked "insufficient funds." But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation.
So we have come to cash this check -- a check that will give us upon demand the riches of freedom and the security of justice. We have also come to this hallowed spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to open the doors of opportunity to all of God's children. Now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood.
It would be fatal for the nation to overlook the urgency of the moment and to underestimate the determination of the Negro. This sweltering summer of the Negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. Nineteen sixty-three is not an end, but a beginning. Those who hope that the Negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to business as usual. There will be neither rest nor tranquility in America until the Negro is granted his citizenship rights.
The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges. But there is something that I must say to my people who stand on the warm threshold which leads into the palace of justice. In the process of gaining our rightful place we must not be guilty of wrongful deeds. Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.
We must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. Again and again we must rise to the majestic heights of meeting physical force with soul force.
The marvelous new militancy which has engulfed the Negro community must not lead us to distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny and their freedom is inextricably bound to our freedom.
We cannot walk alone. And as we walk, we must make the pledge that we shall march ahead. We cannot turn back. There are those who are asking the devotees of civil rights, "When will you be satisfied?" we can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as the Negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote. No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.
I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow cells. Some of you have come from areas where your quest for freedom left you battered by the storms of persecution and staggered by the winds of police brutality. You have been the veterans of creative suffering. Continue to work with the faith that unearned suffering is redemptive.
Go back to Mississippi, go back to Alabama, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed. Let us not wallow in the valley of despair. I say to you today, my friends, that in spite of the difficulties and frustrations of the moment, I still have a dream. It is a dream deeply rooted in the American dream.
I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal." I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at a table of brotherhood. I have a dream that one day even the state of Mississippi, a desert state, sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today.
I have a dream that one day the state of Alabama, whose governor's lips are presently dripping with the words of interposition and nullification, will be transformed into a situation where little black boys and black girls will be able to join hands with little white boys and white girls and walk together as sisters and brothers. I have a dream today. I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together. This is our hope. This is the faith with which I return to the South. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.
This will be the day when all of God's children will be able to sing with a new meaning, "My country, 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim's pride, from every mountainside, let freedom ring." And if America is to be a great nation, this must become true. So let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania! Let freedom ring from the snow capped Rockies of Colorado! Let freedom ring from the curvaceous peaks of California! But not only that; let freedom ring from Stone Mountain of Georgia! Let freedom ring from Lookout Mountain of Tennessee! Let freedom ring from every hill and every molehill of Mississippi. From every mountainside, let freedom ring.
When we let freedom ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual, "Free at last! free at last! thank God Almighty, we are free at last!

Can You Guess This TV Theme? #29 - Answer
Tim Allen plays Tim 'The Tool Man' Taylor, a bumbling husband and father of three.... Here's the twist, you see, 'The Tool Man' has his own television show called 'Tool Time', but he's extremely clumsy and was always trying to add more power to more tools, and he hurts himself while building something in almost every episode....
Thank goodness he had his sidekick Al Borland, played by Richard Karn (the Family Feud guy), and his wise neighbor, Wilson Wilson, who was only seen from the nose up throughout the run of the show, to keep him on the straight and narrow....
No matter what kind of ridiculous situations Tim Taylor was able to bring on himself, his wife, played by Patricia Richardson, and his kids, played by Zachery Ty Bryan, Jonathan Taylor Thomas and the other kid who became a goth in the later seasons of the show, always stood by his side....
Apparently, very few people hated the show during its eight season run.... At it's worst, 'Home Improvement' was 10th in the Nielsen Ratings, and allegedly Tim Allen was offered $50 million and Patricia Richardson was offered $25 million to stay for a 9th season. A wee bit more then I would have offered, but America loves a grunting, power tool obsessed man.... Although the show did jump start Pamela Anderson's blockbuster television career!

Lhermitte-Duclos disease
Findings
There is a small amount of increased signal on FLAIR and T2-weighted images with mild post contrast enhancement in the right cerebellar hemisphere. No mass effect is seen. Contrast images show an incidentally noted venous developmental anomaly on the right draining into the sylvian vein.
Differential diagnosis for the cerebellar lesion:
- Low-grade glioma
- Medulloblastoma
- Pilocytic astrocytoma
- Ganglioglioma
- Lhermitte-Duclos disease
- Cerebellar stroke
Diagnosis: Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum)
Key points
Lhermitte-Duclos disease (LDD) is a very rare benign cerebellar mass
Often associated with Cowden Syndrome–macrocephaly; benign breast, skin, and thyroid lesions; oral papillomas; GI tract hamartomas/polyps; cataracts; genitourinary neoplasia
Lesions grow very slowly or not at all
May cause obstructive hydrocephalus–presentation is usually vague neurologic symptoms related to hydrocephalus
Most commonly present at age 30-40, but can present from birth to age 60
Treatment–surgery for symptomatic patients
Rare recurrence, although complete resection is almost never possible
If confirmed LDD, no followup is needed unless patient is symptomatic
Radiologic appearance
- Well-defined cerebellar mass with striated or "gyriform" appearance
- CT–hypo dense cerebellar mass with hyper dense striations, rare enhancement
- MR
Striated mass with increased T2 and FLAIR signal +/- contrast enhancement
Bright on diffusion weighted images without signal decrease on ADC
MR Spectroscopy–decreased NAA, increased lactate, increased or normal choline
May use MRS to confirm LDD over glioma

Security cameras in newspaper offices in Arcata, California were rolling before and during the magnitude 6.5 earthquake that struck just off the coast of Eureka, California on Saturday, January 9, 2010.....
You can clearly see the dog jumping up and bolting to find its owner before the earthquake occurs..... All reports indicate that the dog and it's owner did get out of the building safely....
Arachnoid cyst with complicating intracystic and subdural hemorrhage
Findings
Figure 1 and Figure 2: Initial non-contrast (Figure 1) and contrast enhanced (Figure 2) axial head CT images. At the level of lateral ventricles an isoattenuating left sided subdural hematoma with mass effect and midline shift is demonstrated. Contrast enhanced imaging shows no abnormal enhancement within the subdural hematoma.
Figure 3 and Figure 4: More inferiorly, a hemorrhagic round extra-axial mass in anterior aspect of the left middle cranial fossa is seen. Bone window image (Figure 4) demonstrates focal thinning with endosteal scalloping of the overlying bone.
Figure 5: Diffusion weighted image through the lesion in the left middle cranial fossa shows no evidence of abnormally restricted diffusion of water. This confirms the lesion is not an epidermoid cyst as they characteristically show intense signal abnormality on DWI.
Figure 6, Figure 7, Figure 8, and Figure 9: The lesion demonstrated isointense signal on T2-weighted imaging (Figure 6). T1-weighted MR imaging (Figure 7) better demonstrates the lesion's complex nature. The lesion represents an arachnoid cyst which shows evidence of hemorrhage as demonstrated by the presence of T1 shortening. The surrounding subdural hematoma shows well demarcated prominent T1 shortening indicative of hemorrhage. Contrast enhanced axial T1-weighted MR imaging (Figure 8) shows no enhancement within the arachnoid cyst but does show enhancement of the dural membrane (arrow). The coronal contrast enhanced T1-weighted MR image (Figure 9) shows the arachnoid cyst, arachnoid membrane, and subdural hematoma.
Diagnosis: Arachnoid cyst with complicating intracystic and subdural hemorrhage
The widespread use of neuroimaging has increased incidental detection of arachnoid cysts. Arachnoid cysts constitute approximately 1% of all intracranial space-occupying lesions. Common locations include the middle cranial fossa, cerebral convexity, perisellar, retrocerebellar, cerebellopontine angle, and quadrigeminal plate cisterns. While some arachnoid cysts arise from post-inflammatory changes after trauma, intracranial hemorrhage, or infection, most are thought to be congenital. It is theorized that these cysts form due to an aberration in arachnoid development resulting in splitting or duplication of the membrane, a defect in condensation of the mesenchyme, or abnormalities of CSF flow. The exact means of arachnoid cyst genesis remains unclear.
On both CT and MRI scans arachnoid cysts are non-enhancing well-circumscribed extra-axial lesions with the same attenuation (on CT) or signal (on all MRI pulse sequences) as that of CSF. Bony erosion and remodeling, features suggestive of longstanding processes, are often associated with arachnoid cysts. These findings are seen in nearly half of cases, and are felt to be secondary to chronic fluid accumulation with transmitted CSF pulsations. Adjacent deformity or even hypoplasia of the subjacent brain may be present depending on the size and location of the cyst.
Rare complications of arachnoid cysts such as intracystic hemorrhage, subdural hematoma, or subdural hygroma may occur either after head injury or spontaneously. Rupture of the outer arachnoid cyst wall and surrounding fragile veins allows blood to accumulate within the cyst and/or subdural compartment. Intracystic hemorrhage can also be due to interruption of the highly vascular arachnoid cyst membrane or of the bridging veins traversing the cyst cavity. Fluid production by flat arachnoid cells lining the cyst walls may explain spontaneous cyst enlargement and hemorrhage if sufficient intracystic pressure is attained to breech the wall and disrupt the vasculature.

All Right Mr. President! I'll Get My Own Fries!
I know I've posted this before, but we're one week away from the anniversary of Barack Obama being inaugurated as the President of the United States, and these clips are awesome....
Who knew the President was such a potty mouth? Before I heard these, I would never have read any of Barack Obama's books, but now I want to read every single one! Here are some clips of Barack Obama reading from his book "Dreams From My Father". Apparently he's quoting a close friend from his youth. These are going to be my ringtones for a long time!
P.S. If you do not like foul language, do not listen to these clips.
