title: Intrahepatic biliary cystadenoma presenting with obstructive jaundice.
abstract: Biliary cystadenoma (BCA) is a rare neoplasm of the bile duct with malignant potential. We report a case of intrahepatic BCA with an unusual presentation of obstructive jaundice. Computed tomography scan of the abdomen revealed a dilated common bile duct and intrahepatic ducts with internal septa. Endoscopic retrograde cholangiography showed an oval filling defect in the bile duct causing the obstruction. At laparotomy, this proved to be a multiloculated mucinous polyp in the common bile duct, with its origin in the left intrahepatic duct, detected using intraoperative choledochoscopy. A left hemihepatectomy was performed, and histology confirmed intrahepatic mucinous BCA with mesenchymal stroma. The imaging process and surgical options for BCA are discussed.
