Hepatic artery aneurysms: Evaluation using three-dimensional spiral CT angiography

Abstract

Hepatic artery aneurysms are rare and frequently difficult to diagnose. Computed tomography (CT) and ultrasound rarely make the definitive diagnosis and angiography is usually required. We present three cases of hepatic artery aneurysms in which the definitive diagnosis was made on three-dimensional (3-D) spiral CT angiography-to our knowledge, this has not previously been described. Our experience shows that in many cases of hepatic artery aneurysm, conventional angiography need only be performed as a prelude to embolization.
