Arteriovenous malformations are a rare cause of gastrointestinal bleeding. Endoscopic examination can result in a variety of findings, and diagnosis and therapeutic management are uniquely challenging. We present an 83‐year‐old man with a history of hypertension and a 1‐month history of intermittent tarry stools. Esophagogastroduodenoscopy revealed one bulging mass with pulsation in the second portion of the duodenum which was confirmed as a duodenal arteriovenous malformation by angiography. The mass was initially embolized successfully, but subsequent surgical intervention was necessary due to recurrent bleeding eight months after the embolization. A relevant review of English medical literature was also performed in the text.
