Focal intrahepatic strictures: A proposal classification based on diagnosis-treatment experience and systemic review

Figure 6 Magnetic resonance cholangiopancreatography images (A and B) and pathological manifestations (C) of patient No. 5 with small duct primary sclerosing cholangitis. Magnetic resonance cholangiopancreatography showed suspected multiple strictures within the biliary tree (orange arrow). Pathological examination showed preserved lobular architecture, moderate fibrosis and inflammatory processes with proliferation of ductules and feathery degeneration of hepatocytes (C). Endoscopic retrograde cholangiopancreatography (ERCP) images (D and E) and pathological manifestations (F) of patient No. 6# with AIH. ERCP showed multiple strictures of intrahepatic bile ducts in both lobes (D and E). Pathological examination showed typical chronic cholestatic hepatitis and infiltration of lymphocytes, mononuclear cells and plasma cells in the periportal area (F).
