A rare surgical case of metachronous double carcinoma of the biliary tract.

We report on a rare case of metachronous double carcinoma of the biliary tract, occurring in a 65-year-old male. The patient was admitted to the hospital with jaundice in March 2004. Ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) scans of the abdomen showed a minimally dilated intrahepatic biliary tree with normal-appearing choledocus.
