Dieulafoy's lesion is a rare cause of severe gastrointestinal bleeding. In most cases, Dieulafoy's lesion is typically found in the stomach within 6 cm from the gastroesophageal junction, but the presence of lesions has also been described throughout the gastrointestinal tract. A jejunal Dieulafoy's lesion is extremely rare, and only a few cases have been reported in the Korean population. We experienced a case of a jejunal dieulafoy's lesion mimicking a submucosal tumor that presented with massive gastrointestinal bleeding. The lesion was diagnosed by the use of double balloon enteroscopy and was then confirmed by a pathological examination of the surgical specimen.
