Hepatic artery aneurysm: CT and MR features

Abstract

The authors report a case of common hepatic artery aneurysm diagnosed by computed tomography (CT) and magnetic resonance (MR). Features of both techniques are described and discussed. The surgical and radiologic literature is reviewed.

Congenital hepatic artery aneurysm: A case report in early infancy

“…Color Doppler ultrasound also can differentiate aneurysm from other vascular abnormalities such as arteriovenous fistulas or malformations (2,4). A three-dimensional spiral CT may allow a definitive diagnosis to be made prior to angiography (2,3,12,13). Appropriate management of HAA requires detailed angiography (2,14).…”

Intrahepatic hepatic artery aneurysm: Computed tomography and color-flow Doppler ultrasound findings

“…Multiple recent publications have described the appearance of HAA on noninvasive studies [4][5][6][7]. Multiple recent publications have described the appearance of HAA on noninvasive studies [4][5][6][7].…”

“…Multiple recent publications have described the appearance of HAA on noninvasive studies [4][5][6][7]. The magnetic resonance appearance of HAA has recently been described [5]. Although highly suspicious for arterial aneurysm this appearance could be shared by a highly vascular neoplasm, venous aneurysm, or arteriovenous malformation.…”

Upper Gastrointestinal Hemorrhage from Hepatic Artery Pseudoaneurysm Secondary to Trauma: A Case Report

“…Bleeding is often intermittent and it may be necessary to repeat the US. Occasionally a large aneurysm may be diagnosed by CT or magnetic resonance imaging [8] . Although HAP has been incidentally detected by endoscopic retrograde cholangiopancreatography, this procedure is not routinely recommended.…”
