Pancreatic pseudocyst is a fluid-filled sac in the abdomen, which sometimes also contains tissues, enzymes and blood from pancreas. Pancreatic pseudocyst occurs usually in a patient with chronic pancreatitis. It may also oocur in people with pancreas injury or after trauma to abdomen. Pancreatic pseudocyst develops when the pancreatic ducts are damaged by the inflammation that occurs during pancreatitis. Unlike true cysts, pseudocyst are not lined by epithelium but with with granulation tissue. Other complication arising because of pancreatic pseudocyst includes infection, hemorrhage, obstruction, rupture, compression in urinary system, biliary system, and arteriovenous system.
