Bile duct cysts secondary to liver infarcts: report of a case and experimental production by small vessel hepatic artery occlusion.

Hepatic bile duct cysts were demonstrated on an abdominal CT scan and confirmed at autopsy in a patient with polyarteritis nodosa. The cysts developed in close proximity to hepatic artery aneurysms and occlusions visualized at hepatic arteriography and confirmed postmortem. The development of similar bile duct cysts following hepatic artery occlusion was demonstrated in 13 Rhesus monkeys.
