Sonographic appearance of extensive hepatic arterial calcification mimicking pneumobilia.

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.
