ObjectiveTo improve the recognition of intrahepatic biliary cystadenoma.
MethodsThe clinical manifestations,radiologic features,diagnosis and surgical treatment of 18 patients with intrahepatic biliary cystadenoma admitted in our hospital during the recent 8 years were retrospectively analyzed.
ResultsFour cases were discovered by general medical examination, while the other 14 patients had varying symptoms that included right upper abdominal discomfort or pain in 11 cases, abdominal mass in 3 cases,and jaundice accompanied by fever in 2 cases. B ultrasound and CT scan showed intrahepatic cystic occupying lesions consisting of multilocular or single cyst,and usually with papillary structures in the cyst wall. All of 18 cases received surgical resection. The patholgic dingnosis was intrahepatic biliary cystadenoma in all the 18 cases, and 6 of them showed malignant change.The average survival time of maligmant patients was 35(27-58)months.
ConclusionsPreoperative diagnosis of intrahepatic biliary cystadenoma is difficult.Intrahepatic biliary cystadenoma is easy to develop into cystadenocarcinoma. Early surgical resection is necessary, and can effectively prevent recurrence or malignant transformation.
