Rupture of a Bleeding Pancreatic Pseudocyst into the Stomach: a Case Report

Pancreatic pseudocyst is a well-known complication of pancreatitis. However spontaneous perforation and/or fistularization is rare. Perforations into the free peritoneal cavity, stomach, duodenum, colon, portal vein, pleural cavity, and through the abdominal wall have been reported. Rupture of pseudoaneurysm or bleeding pseudocyst following pancreatitis is a severe complication that can lead to massive gastrointestinal bleeding. Especially, rupture of a bleeding pseudocyst into the stomach combined with splenic artery pesudoaneurysm is very rare. We experienced a case of massive bleeding from pancreatic pseudocyst with pseudoaneurysmal rupture into the stomach which was controlled nonoperatively by splenic artery coil embolization and conservative treatment. We report the case with the literatures review.
