Abstract

Splenic artery aneurysm is an uncommon clinical entity. Most of these aneurysms are asymptomatic, but if an aneurysm ruptures, it can be fatal and its mortality rate reaches 70 percent. Regardless of the presence of symptoms, if the size of the asymptomatic aneurysm is larger than 2 cm in diameter or the patient is pregnant, then the anurysm should be treated. A 74-year-old female visited our hospital complaining of nonspecific epigastric discomfort. Endoscopic examination of the stomach revealed a submucosal tumor like protruding mass in the body and it was finally diagnosed as a splenic artery aneurysm by computed tomography. We report here on a case of a splenic artery aneurysm that mimicked a submucosal tumor, and this aneurysm was treated with surgery. (Korean J Gastrointest Endosc 2009;38:142-146)
