Ependymoma-MRI

Intracranial ependymomas are typically isodense on unenhanced CT scans with minimal to moderate enhancement upon contrast administration. Calcification can be noted on unenhanced CT scans in approximately one half of cases. Cyst formation is common in these tumors, and foraminal spread can be observed in posterior fossa lesions through the foramina of Luschka and Magendie. On precontrast and postcontrast MRI, tumors often appear heterogeneous secondary to necrosis, hemorrhage, and calcification. Variable signal intensity is noted on T1- and T2-weighted images although intracranial ependymomas are usually hypointense to isointense on T1-weighted images and hyperintense compared with gray matter, on T2-weighted images.
