title: Biliary Cystadenoma: A Case Report.
abstract: Biliary cystadenoma is a rare cystic neoplasms of liver that usually occurs in middle-aged women characterized by multiloculated cysts with internal septae and mural nodules. Unilocular biliary cystadenomas are rare and are difficult to differentiate from other cysts by radiology. Biliary cystadenomas are slow growing benign lesions that are easily resectable with a reported recurrence rate of 90% when the resection is incomplete. We present a case of 65-year-old male with unilocular biliary cystadenoma with mesenchymal stroma who presented with abdominal pain and distension. Laparotomy followed by cystectomy was done and postoperative period was uneventful with no abnormal biochemical, heamatological or imaging findings. Preoperative radio-imaging techniques may not always be helpful in arriving at a specific diagnosis in such cases. Hence thorough sampling and a careful histopathological examination is considered gold standard for specific diagnosis.
