Upper gastrointestinal bleeding caused by arteriovenous malformation (AVM) has been rarely described in the literature and usually presents as massive hematemesis or chronic iron deficiency anemia. Case Report: We report the case of a 43-yearold man with no medical history, who suffered from gastrointestinal bleeding. The bleeding source was a gastric arteriovenous malformation emerging from the splenic artery identified by computed tomography angiography (CTA) scan. This malformation was responsible of portal hypertension and splenic artery aneurysm. Therapeutic angiography succeeded in occluding the vessel. Conclusion: Nonspecific endoscopic appearances make the diagnosis difficult. Therapeutic embolization offers a better chance of stopping hemorrhage.
