Pancreatic Cystic Lesions

Research output: Chapter in Book/Report/Conference proceedingChapter


Pancreatic cysts are relatively rare lesions, and their diagnosis has increased with the widespread availability and use of cross-sectional imaging. In many cases pancreatic cysts are detected on imaging performed for another indication; however, they can also be seen in patients with symptoms such as abdominal pain or jaundice. The majority of pancreatic cystic lesions are nonneoplastic cysts, which are predominantly pancreatic pseudocysts (PPs) and are mostly seen as a local complication of pancreatitis. Neoplastic cysts of the pancreas are broadly categorized as mucinous and nonmucinous lesions, and the type of epithelial lining determines the risk of malignancy. Once a PP has been eliminated as a possibility, the next step is to determine the type of cyst based on cross-sectional imaging, aspiration cytology, and cyst fluid analysis.
