Abstract
Autoimmune pancreatits is highly associated with sclerosing cholangitis. We call these sclerosing cholangitis as autoimmune sclerosing cholangitis, which can be classified into four types. Cases with cholangiogram showing diffuse stenoses in the intrahepatic bile ducts are misdiagnosed as primary sclerosing cholangitis and localized stenosis may be misdiagnosed as cholangiocarcinoma. Detailed examination of cholangiographic findings in autoimmune sclerosing cholangitis elucidated some different points from those of primary sclerosing cholangitis. We concluded that cholangiography is useful in differentiating autoim-mune sclerosing cholangitis from primary sclerosing cholangitis.
