ABSTRACT
Cholangiographic features of PSC include the following:
1. Band strictures (as in this case) leading to a beaded appearance
2. Nonuniform, segmental strictures 1 to 2 cm long 3. Pruned-tree appearance of intrahepatic ducts (due to
obliteration of ducts) 4. Diverticular outpouchings 5. Mural irregularity-this can vary from fine to shaggy
contour changes 6. Combinations of the above
Findings A. ERCP. B. MRCP. Diffuse long strictures are present throughout the intrahepatic ducts. The extrahepatic ductal system is normal in appearance.
