Magnetic resonance cholangiopancreatography with maximum intensity projection. There is mild intrahepatic and extrahepatic bile duct dilatation. There is a long segment 2.9 cm stricture of the hilar common hepatic duct (arrows). A linear filling defect within the common bile duct is consistent with a known biliary stent (arrowhead). Peribiliary mass (asterisk) measuring up to 1.5 x 1.2 cm is unchanged, abutting the right portal vein, inferior vena cava, and pancreatic head, and replacing the right hepatic artery. Postcontrast enhancement is noted throughout the common bile duct.
