A Case of Jejunal Dieulafoy’s Lesion Mimicking Submucosal Tumor with Hemorrhagic Shock

Abstract

Small intestinal Dieulafoy’s lesion is a relatively rare disease and is often known to cause major bleeding ; herein, we report a case in which we carried out resection of a small-intestinal Dieulafoy’s lesion. The patient was a 60-year-old woman who was hospitalized for massive melena. Abdominal contrast CT showed extravasation in the jejunum and a double-balloon enteroscopy revealed a 10-mm pulsatile submucosal tumor-like elevation in the small intestine, which we diagnosed as the bleeding source. Because endoscopic hemostasis was impossible, partial resection of the jejunum was performed. Histopathological findings showed dilated arteries in the submucosal layer and lesioned arteries with arterial lesions? based on which we made the diagnosis of Dieulafoy’s lesion.
