Massive gastric bleeding from pancreatic pseudocyst, caused by rupture of pseudoaneurysm

Massive bleeding into a pancreatic pseudocyst is an unusual but life-threatening clinical condition. In this report, we present a case of massive gastric hemorrhage from a pancreatic pseudocyst, caused by rupture of a pseudoaneurysm of the splenic artery. The patient was successfully managed by total gastrectomy with splenectomy and distal pancreatectomy. Of a total of 66 cases in our Japanese literature review, only 5 cases of gastric hemorrhage associated with pancreatic pseudocyst have been reported, including the case herein presented. Diagnosis and therapeutic strategy are discussed.
