Figure 8 Classification of immunoglobulin G4-related sclerosing cholangitis biliary strictures[9].
Type 1 stricture confined to the intrapancreatic bile duct. Type 2 diffuse strictures involve both intrahepatic and extrahepatic bile ducts. Subtype 2a: Intrahepatic duct strictures with prestenotic dilation. Subtype 2b: Intrahepatic duct strictures without prestenotic dilation and with decreased biliary arborization. Type 3 combined strictures of the hilar bile ducts and the intrapancreatic bile duct. Type 4 isolated strictures of the hilar bile ducts. Arrow(s) indicate the location of the bile duct strictures.
