Overview

A pancreatic pseudocyst is a circumscribed collection of fluid rich in amylase and other pancreatic enzymes, blood and necrotic tissue typically located in the lesser sac. It has a non-epithelialised lining made of granulation tissue and hence the name pseudocyst (pseudo - false). By contrast, true cysts have an epithelial lining. This is typically a complication of acute pancreatitis, but may also occur following abdominal trauma.
