Visceral artery aneurysmosis. Case report.

Visceral artery aneurysms have been reported which involve most major visceral arteries. However, these are usually isolated and limited to one or, at most, two visceral vessels or are related to specific systemic disorders such as the collagen vascular diseases. we have identified a patient who presented with an asymptomatic upper abdominal mass which proved upon angiography to be a splenic artery aneurysm. The patient also proved to have aneurysms of the superior mesenteric artery, the left and right hepatic arteries and the gastroduodenal artery. Histologic examination revealed normal and elastic tissue content of the vessels. Review of the literature has not revealed a similar type of case of multiple aneurysmal degeneration of visceral arteries as domonstrated by this case.
