Klatskin tumor presenting as unresectable perihilar hepatic mass: A case report.

Cholangiocarcinoma is a rare liver tumor with three types: intrahepatic, extrahepatic, and perihilar, which alone account for about 50% of cases. The diagnosis is late with a poor prognosis. Imaging through Bili MRI and CT scan plays an essential role in the classification and staging of tumors for therapeutic management. We report the case of a 62-year-old woman, received for cholestasis syndrome and weight loss in whom CT and MRI found a hepatic hilar mass. The diagnosis of Klatskin's tumor was retained with a histological finding of adenocarcinoma. The patient underwent biliary drainage and palliative treatment as the tumor was unresectable.
