Context: Visceral pseudoaneurysm is a rare but serious complication of chronic pancreatitis. Usually the pseudoaneurysm involves the splenic artery, the pancreaticoduodenal or the gastroduodenal artery. Only a few cases have been reported on left gastric pseudoaneurysm causing gastrointestinal bleeding. Case Report: We report a case of a 32-year-old male with chronic pancreatitis that presented with history of passing intermittent episodes of bright red blood per rectum. An abdomen-pelvis computed tomography was obtained, showing a large left gastric pseudoaneurysm that was communicating with a 4cm pancreatic pseudocyst. The patient underwent successful angiographic coiling/exclusion of the aneurysm. Conclusion: Patients with history of pancreatic pseudocysts or chronic pancreatitis that present with gastrointestinal bleeding should have a computed axial tomography of the abdomen-pelvis to rule out pseudoaneurysms of the pancreatic vessels. The mortality of these pathologies is as high as 50% and they could be missed when performing only upper endoscopy and colonoscopy.
