Perivascular enhancement Cavernous transformation of the portal vein Cholangitis (PSC, Pyogenic cholangitis, Viral cholangitis, AIDS-related cholangitis, Recurrent pyogenic cholangitis) Hepatitis Cholangiocarcinoma Metastases Periportal fibrosis (Congenital hepatic fibrosis, Schistosomaisis, Sarcoidosis) C.
