Figure 1 Imaging examinations. A: Dynamic computed tomography (case 1) showing common bile duct wall thickening at the ductal confluence (circle) and mild dilatation of the intrahepatic bile duct; B: Magnetic resonance cholangiopancreatography showing stricture of common bile duct (arrow) and dilatation of the intrahepatic bile duct; C: Dynamic computed tomography (case 2) showing bile duct wall thickening at the upper pancreatic margin level (circle) with dilatation of the entire bile duct system without pancreatic duct dilatation; D: Magnetic resonance cholangiopancreatography showing stenosis of the distal common hepatic duct (arrow) and dilatation of the intrahepatic bile duct.
