Magnetic resonance imaging diagnosis of hilar cholangiocarcinoma

Hilar cholangiocarcinoma (HCCA) or Klatskin tumor is a scirrhous adenocarcinoma that arises from the conjunction of bile duct and hepatic ducts. Hepatic magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) are important methods for the diagnosis of HCCA. In this article, the clinical data of 42 patients in the Changhai Hospital and 18 patients in the Eastern Hepatobiliary Surgery Hospital who received MRI and MRCP examination from October 2010 to October 2012 were retrospectively analyzed. According to the pathological features, HCCA could be divided into massforming type, infiltrating type and intraductal type. Based on the results of imaging examination and intra- and postoperative pathological examination, BismuthCorlette types were decided pre and postoperatively. The coincidence rate of pre- and postoperative BismuthCorlette types was 89.7%(35/39).
