Biliary cystadenomas and cystadenocarcinomas have an immunohistochemical profile similar to pancreatobiliary cystadenomas and cystadenocarcinomas." The epithelium typically shows staining for CK7, CK20, AE1/AE3, CEA, CA 19-9, and CA125." Ovarian-type stroma may be present and may show staining for pro-...

These lesions include simple (bile duct) cyst, autosomal dominant polycystic liver disease, biliary hamartoma, Caroli s disease, pyogenic and amoebic abscesses, intrahepatic hydatid cyst, biliary cystadenoma and cystadenocarcinoma, cystic subtypes of primary liver neoplasms, cystic metastases, and intrahepatic hematoma and biioma. 

At CT, a biliary cystadenoma appears as a solitary cystic mass (5-25 HU) with a well-defined thick fibrous capsule, mural nodules, internal septa, and rarely capsular calcification (Buetow and Midriff 1997 Palacios et al. 1990). Polypoid, pedunculated excrescences are seen more commonly in biliary...

Biliary cystadenoma and biliary cystadenocardnoma are rare neoplasms of the liver and comprise less than 5% of intrahepatic cysts of biliary origin (Ishak et al. 1977). Cystadenocardnoma develops mostly in hepatic cystadenoma Most of the reported cases are in middle-aged women (Devaney et al. 1994). Clinical symptoms are abdominal pain, mass, and intermittent... 

First of all biliary cystadenocarcinoma with ovarian stroma, containing a typical band of closely bound spindle cells below the epithelium. This type is documented only in women developing from a preexisting biliary cystadenoma.
