Dieulafoy's lesion is a rare vascular abnormality characterized by a small abnormally dilated artery that runs a tortuous course in the submucosa. There is usually no ulcer present in Dieulafoy's lesions and the overlying mucosa is most often normal. Bleeding caused by a Dieulafoy's lesion is usually urgent, massive, life-threatening and prone to recurrence. Dieulafoy's lesions have been reported throughout the digestive tract although the majority of them have been found in the upper digestive tract especially the stomach and duodenum. However, a Dieulafoy's lesion occurring inside a duodenal diverticulum is very rare.
