Abstract

Biliary cystadenoma is a rare cystic tumour of biliary origin. We report on the ultrasound, CT and angiographic appearances of an extra-hepatic biliary cystadenoma arising from the left main hepatic duct with compression of the quadrate lobe. We also describe the histological finding of adenomyomatosis of the gall-bladder in association with the cystadenoma, an association not previously reported.
