Sonographic appearance of extensive hepetic arterial calcification mimicking pneumobilia

Abstract
Pneumobilia appears sonographically as intrahepatic linear echogenic regions that often produce distal acoustic shadowing. We present a case in which extensive hepatic arterial calcification mimicked the sonographic appearance of pneumobilia. In the appropriate clinical setting, extensive hepatic arterial calcification should be considered when intrahepatic linear echogenic regions are found sonographically. © 2002 John Wiley & Sons, Inc.
