[Radioisomorphisms of sclerosing cholangitis]

For differentiation of Primary Sclerosing Cholangitis (PSC) from AIDS-associated cholangitis (AAC), 95 CT or Cholangiography studies of 37 patients were reviewed and signs of biliary disease analysed. Only two each of PSC and AIDS-subjects were free from biliary lesions compatible with some kind of sclerosing cholangitis. Subgroup analysis revealed wide overlapping of morphological findings in PSC and AAC. We conclude that radioisomorphism of etiologically different forms of sclerosing cholangitis may indicate pathophysiologically similar courses.
