A case of biliary cystadenocarcinoma with recurrent jaundice. Diagnostic evaluation of computed tomography

A 73-year-old male patient with biliary cystadenocarcinoma and episodes of recurrent jaundice is reported. This very rare tumor was suggested as a possible diagnosis by the computed tomographic findings showing intrahepatic cystic masses with septations and papillary projections. The diagnosis of the mucin-producing tumor was supported by aspiration of mucinous bile with a cannule inserted endoscopically via the major duodenal papilla. The computed tomographic findings and the diagnosis were verified by pathologic studies made on the material obtained surgically. The mucinous bile is assumed to have been responsible for the recurrent jaundice.
