A pseudocyst is not a true cyst because the wall of the sac does not consist of a specific lining of cells that is characteristic of a true cyst. The most common cause of a pancreatic pseudocyst is an inflammation of the pancreas, called pancreatitis. A less common cause or contributor is trauma, such as a blow to the stomach. Pancreatitis is most commonly caused by alcohol abuse and gallstones.
