title: The Hidden Culprit in a Massive Episode of Hematemesis: A Dieulafoy's Lesion.
abstract: A Dieulafoy's lesion is described as a tortuous, dilated aberrant submucosal vessel that can penetrate through the mucosa and rupture spontaneously, resulting in severe gastrointestinal bleeding. The lesion is most commonly found in the proximal stomach. Historically, it has had up to an 80% mortality rate because of its tendency to cause intermittent but severe bleeding and diagnostic challenges. We report a case of a young male with recurrent severe upper gastrointestinal bleeding with extensive prior investigations failing to reveal the source of bleeding. Computed tomography angiography of the abdomen correctly identified Dieulafoy's lesion of the stomach, and it was subsequently confirmed and successfully treated with interventional radiology (IR)-guided mesenteric angiography and embolization.
