Hepatic artery pseudoaneurysm secondary to a cholangitic abscess and its spontaneous thrombosis

Abstract

Hepatic artery pseudoaneurysm (HAP) is mostly encountered secondary to trauma or iatrogenic causes. HAP associated with cholangitic liver abscess is a rare complication. We present a case of gallstone disease and choledocholithiasis who developed moderate cholangitis and a liver abscess. A small HAP was detected incidentally on a biphasic CT done to evaluate the biliary system. Repeat CT after management with endoscopic retrograde cholangiopancreatography and antibiotics showed resolution of cholangitic abscess with spontaneous thrombosis of HAP.
