A Case of a Spontaneous Hemoperitoneum as the Presentation of a Gastric Arteriovenous Malformation / 대한소화기내시경학회지

Spontaneous hemoperitoneum is rare. The most common etiologies are gynecologic, splenic, and hepatic. Gastric arteriovenous malformations are commonly associated with intraluminal bleeding, but gastric arteriovenous malformations are an unusual cause of spontaneous intraperitoneal hemorrhage. A 54-year-old man presented with acute onset of epigastric pain. The patient was given an operation and pathology confirmed that it was a gastric arteriovenous malformation.
