Infiltrative hilar cholangiocarcinoma in a patient with progressive jaundice. A axial (a) and coronal (b) T2-weighted image showed wall thickening of bile duct at the hepatic hilar level, and the left hepatic ducts were dilated. In (c) and out (d) of phase imagings showed no change on the signal intense of liver background. The hepatocellular phase (e) showed nearly no Gd-EOB-DTPA in the common bile duct. The biliary phase (f) showed that there was little Gd-EOB-DTPA in the common bile duct, indicating that the function of biliary system was abnormal.
