A Huge Gastric Angiolipoma Presenting with Acute Upper Gastrointestinal Hemorrhage: A Case Report

Abstract

Background: Angiolipoma is a benign neoplasm mainly composed of adipose tissue and proliferating blood vessels and is relatively rare in the gastrointestinal tract. And among them, gastric angiolipomas are extremely rare and tend to be small.

Case presentation: We report the clinical and imaging features of a patient with a huge angiolipoma in the stomach and an episode of hematemesis and melena, caused by the ulceration of the gastric mucosa overlying the gastric subepithelial angiolipoma revealed by the endoscopic evaluation. The patient was anemic, and the anemia resolved after local surgical resection of the tumor. We also reviewed the imaging and histological features of the presenting gastric angiolipoma.

Conclusion: Radiologists should be aware of this rare benign gastric tumor that may present with gastrointestinal hemorrhage.
