Jejunal Dieulafoy Lesion: A Rare Cause of Lower Gastrointestinal Bleed

Dieulafoy lesions are becoming increasingly more recognized as a cause of acute gastrointestinal bleeding as advances in endoscopic techniques have improved detection and treatment of such lesions. Responsible for nearly 2% of all gastrointestinal (GI) hemorrhages, the vast majority of Dieulafoy lesions are located in the upper GI tract, particularly the stomach. Only 1-2% of such lesions are found in the jejunum; thus, these lesions are not commonly considered in the differential diagnosis of lower GI bleeds. Here we present the case of an 83-year-old woman, with a history of recurrent GI bleeding secondary to arteriovenous malformations, who presented with an acute lower GI bleed due to a jejunal Dieulafoy lesion.
