title: Biliary cystadenoma and cystadenocarcinoma: two rare cystic liver lesions.
abstract: A case of hepatobiliary cystadenoma with mesenchymal stroma and a case of biliary cystadenocarcinoma are presented. Hepatobiliary cystadenoma and cystadenocarcinoma are rare liver lesions that are difficult to diagnose preoperatively. Regardless of the diagnostic modalities used these two pathologies cannot be differentiated with accuracy. The preoperative diagnosis of biliary cystadenoma and cystadenocarcinoma was suggested due to the radiological detection of vascularity in the septa and the invasion of the thoracoabdominal wall. The surgeon was informed in both of the cases. Pathologic examination confirmed the diagnosis in both of our patients. The radiological features of these pathologies are discussed in detail together with a brief review of the literature.
