Hepatic artery aneurysm: a rare cause of obscure upper gastrointestinal bleeding

Hepatic artery aneurysms are rare and represent 0.01-0.2% of all arterial aneurysms. The patient may present with abdominal pain, which may be associated with a mass. More acutely, patients present with signs of hypovolemia secondary to rupture of the aneurysm. The patient reported here presented with right upper abdominal pain and gastrointestinal hemorrhage of unknown etiology. A CT angiogram showed presence of hepatic artery aneurysm. Aneurysm was excised at laparotomy.
