Diagnostic and intervention radiology perspective of Dieulafoy’s lesion of stomach – A case report with literature review

Dieulafoy’s lesion is a developmental vascular malformation of the gastrointestinal (GI) tract. It is a relatively uncommon cause of life-threatening GI bleeding from a dilated and tortuous submucosal artery in the absence of mucosal ulcers or erosions. With the proactive use of endoscopy-guided intervention, the mortality of the condition can be reduced. In endoscopically negative cases, imaging plays a pivotal role in diagnosing it, which can then be treated by endovascular embolization. We report a case of middle-aged female who presented with acute hematemesis. Endoscopy showed trace active oozing from a mucosa in the cardia of the stomach, in the absence of appreciable ulcer, erosion, or mass lesion. On contrast computed tomography abdomen, we detected a Dieulafoy’s lesion in the fundus of the stomach, which was then promptly embolized by endovascular route. The clinical details, imaging appearance, and treatment of this uncommon lesion are discussed here.
