IgG4-related Sclerosing Cholangitis Presented as a Mass in the Liver / 대한췌담도학회지

ABSTRACT

Autoimmune pancreatitis or IgG4-related sclerosing cholangitis often involves the liver. Most common lesion involving the liver is shown as mass or masses often referred as inflammatory pseudotumor. Inflammatory pseudotumor usually needs to be discriminated with malignancy. Here we report a case of IgG4-related sclerosing cholangitis with liver involvement presented as a mass. It was proven by biopsy and did not show any evidence of autoimmune pancreatitis. The mass infiltrated around the portal tract and portal vein thrombosis was also present.
