A pancreatic pseudocyst is a collection of tissue, fluid, debris, pancreatic enzymes, and blood in the abdomen. It can develop after acute pancreatitis.
Pancreatic pseudocysts usually develop after an episode of severe, acute pancreatitis. They often happen when the pancreatic ducts are disrupted by inflammation that occurs during pancreatitis. Risk factors for a pancreatic pseudocyst are acute pancreatitis, abdominal trauma, and chronic pancreatitis.
