A Case of Arteriovenous Malformation Presented as a Submucosal Tumor / 대한소화기내시경학회지

ABSTRACT

Arteriovenous malformations (AVM) are an unusual cause of gastrointestinal (GI) bleeding. But most GI AVM can occur with GI bleeding. When conventional diagnostic studies have failed to reveal the source of GI bleeding, AVM have been one of the most common causes. But the incidence of AVM presented as bleeding of a gastric submucosal tumor is very low. A case of gastric submucosal tumor was experienced and reported as an AVM. This case is herein discussed with review of corresponding literature.
