Unusual presentation of silently growing abdominal aortic aneurysm causing biliary obstruction.

ABSTRACT

Biliary obstruction is a rare presentation of abdominal aortic aneurysm (AAA). The most common symptoms of AAA are abdominal or back pain and limb ischaemia from thromboembolism. We report a case of a 67-year-old male who was diagnosed with obstructive jaundice secondary to an AAA. CT angiogram revealed compression of the common bile duct by the large AAA, causing diffuse intrahepatic and extrahepatic ductal dilatation. Surgical repair of the aortic aneurysm was successful, and patient's symptoms improved.
