Pseudoaneurysm of the Splenic Artery Presenting with Gastrointestinal Bleeding

Gastrointestinal bleeding from a pancreatic pseudocyst is a rare condition that is diagnostically and therapeutically challenging. A 78-year-old woman with a history of acute pancreatitis due to gallstones was hospitalized for abdominal pain and gastrointestinal bleeding. Gastroscopy revealed blood extruding from the papilla of Vater. A computed tomography scan revealed hemorrhage into a pancreatic pseudocyst. The patient was successfully treated by coil embolization.
