ABSTRACT
Biliary cystadenomas are very rare cystic neoplasms usually arising from the intrahepatic bile ducts. The majority of patients are middle-aged women who present with abdominal discomfort and/or a palpable mass. The diagnosis was performed using several methods such as abdominal ultrasonography, computed tomography, percutaneous cholangiography or endoscopic retrograde cholangiopancreatography, and showed multiloculated cystic tumors with multiple internal septation. But confirmatory diagnosis was done by surgical pathology. Because the prognosis is comparatively better than after complete resection and the cystadenoma is warranted to avoid malignant change, early detection and surgical resection must be needed. We have experienced two cases, 30 and 50 year old females, which presented with nonspecific abdominal pain and dyspepsia. They were diagnosed as having intrahepatic biliary cystadenoma histopathologically which was confirmed after surgical resection. We report two cases of intrahepatic biliary cystadenoma with a review of literature.
