The clinical history of a patient with intermittent jaundice is presented. The diagnostic work up, including ultrasound, laparoscopy, and endoscopic retrograde cholangiography, revealed a multiloculated cystic mass in the left lobe of the liver. At laparotomy, a multicystic lesion invading the left hepatic duct and protruding into the common bile duct was found. Histological examination revealed a biliary cystadenoma. Complete excision is the treatment of choice of such lesions.
