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 due to increased pressure in the pancreatic duct (e.g. stenosis, calculus, protein plugs) or pancreatic necrosis following an episode of acute pancreatitis, but may also occur following abdominal trauma. [1] Pancreatic pseudocyst generally complicates the course of chronic pancreatitis in around 30-40% of the patients.
