Hilar CCA presenting as an intraluminal mass with biliary obstruction. The mass is isodense (arrow) on the coronal non-contrast enhanced CT (a) and hypointense on axial T2-weighted image (b) with upstream dilatation of the intrahepatic ducts. ERCP (c) shows a filling defect (arrow) representing the mass extending into the common bile duct with no filling of the intrahepatic ducts.
