title: [Biliary cystadenoma. A report of 2 cases].
abstract: Two cases of cystadenoma of the biliary tract are presented. This is a rare tumor that represents less than 5% of non parasitic cysts of biliary origin. It usually occurs in middle-aged women. Ultrasound (US) and Computerized Tomography (CT) are most important for tumor diagnosis, but differential diagnosis with other cystic tumors of the liver is very difficult preoperatively. Malignant degeneration to biliary cystadenocarcinoma is documented. Surgery is always indicated and has included aspiration, sclerosis, marsupialization, internal drainage, but the complete removal of lesion with enucleation or liver resection is the treatment of choice.
