Possible Pancreatic Cystosis

1. Pancreatic involvement in cystic fibrosis can result in exocrine or endocrine insufficiency. 
2. The spectrum of pancreatic appearances has been described as follows: complete replacement of the pancreas by fibrofatty tissue, with enlargement of the pancreas corresponding to lipomatous pseudohypertrophy; partial replacement of the pancreas by fibrofatty tissue; complete atrophy of the pancreas without fatty replacement; diffuse pancreatic fibrosis; and cystic transformation of the pancreas. Calcifications may also be found.  
3. Macroscopic cysts measuring more than 1 cm are a rare condition. Macrocysts of different sizes distributed throughout the gland represent an extremely unusual form of pancreatic involvement in CF that has been described in only a few patients and is known as pancreatic cystosis.
