Peritoneal hepatobiliary cystadenoma: Case report

Abstract

Hepatobiliary cystadenoma with mesenchymal stroma are infrequent form of cystic neoplasm that may be found in females only. It is difficult to reach correct diagnosis prior to surgery. We are presenting a case of 32 years-old female referred to our institution for revealing a cause of discomfort and pain in right subcostal region whereas peritoneal hepatobiliary cystadenoma has been determined. Abdominal ultrasonography and computerized tomography revealed cystic lesion adjacent to gall bladder, which was initially thought to be of echynococcal origin. At surgery, a mesenterial cystic neoplasm has been revealed, having a close contact with gall bladder, without signs of its infiltration. Pathophysiology discovered hepatobiliary cystadenoma with mesenchymal stroma. Pre-surgical differential diagnosis in hepatobiliary cystadenoma may be very difficult, especially if, like in the presented case, neoplasm has extra hepatic localization. Radical surgical excision is treatment of choice, concerning malignant potential of these neoplasms.
