Painless obstructive jaundice is often associated with a malignant disease of the common bile duct or head of the pancreas. The authors present a unique case of a 62-year-old woman affected by an intrahepatic cystadenoma that extended into the common biliary duct. To our knowledge no previous case reports have been published on similar cases. After undergoing an en-block hepatic and bile duct resection, this patient is doing well without signs of recurrent disease.
"Biliary cystadenoma involving the extra- and intrahepatic bile ducts simultaneously is less frequent. To our knowledge, there has been one published case  that describes a biliary cystadenoma involving the intrahepatic duct extending to the common bile duct. We aim to highlight here an instance of biliary cystadenoma involving the intra- and extrahepatic bile ducts, which is an uncommon presentation. "
[Show abstract][Hide abstract] ABSTRACT: Biliary cystadenomas are rare tumors of the bile ducts most commonly presenting as large right liver lobe lesions. These are usually slow-growing and mostly benign. They commonly present with abdominal pain. On physical exam an abdominal mass can be identified occasionally. Walls of biliary cystadenomas appear thicker than simple cysts, with soft tissue nodules and enhancing septations on CT or MRI. Radiographic images can vary with the amount of protein content in the fluid on CT or MRI. Due to the risk of malignant transformation, complete surgical resection is advised. Hereby, we describe a 37-year-old lady who presented to the outpatient clinic with bloating and abdominal discomfort with intermittent elevated liver enzymes and hyperbilirubinemia. Ultrasound of the liver and bile ducts followed by CT scan and magnetic resonance cholangiopancreatography confirmed the presence of biliary cystadenoma of the intra- and extrahepatic ducts. It was seen as a filling defect of the intra- and extrahepatic ducts (common hepatic duct) on endoscopic retrograde cholangiopancreatography. Involvement of the intra- and extrahepatic bile ducts simultaneously is a rare presentation of this tumor. She later on underwent exploratory laparotomy with extrahepatic bile duct resection, left hepatic lobe resection and reconstruction with hepaticojejunostomy. Pathology confirmed the presence of biliary cystadenoma with ovarian-like stroma. She had recovered uneventfully from the surgery when seen 2 weeks later in the clinic. Biliary cystadenoma is a rare, mostly benign neoplasm of the biliary tract that should be considered in the differential diagnosis of cystic lesions of the biliary tract.

[Show abstract][Hide abstract] ABSTRACT: The classic presentation of cystic hepatobiliary lesions is usually nonspecific and often identified incidentally. Here we describe the case of a patient presenting with acute pancreatitis resulting from a large centrally located biliary cystadenoma compressing the pancreas. Determination of the origin of the cystic lesion was difficult on imaging studies. Due to the difficult location of the lesion, a complete surgical resection was achieved with mesohepatectomy and the suspected diagnosis confirmed by pathology. The patient continues to do well 2 years post-op with no signs of recurrence.
