In patients with the diagnosis of autoimmune hepatitis (AIH), the presence of cholestatic features raise the possibility of an overlap syndrome with primary sclerosing cholangitis (PSC). Here, we present a unique case with AIH-PSC overlap syndrome and innumerable liver masses.
CASE REPORT: A 26-year-old man presented with generalized icterus. Based on the serological findings of hypergamainmunoglobulinemia and positive anti-nuclear antibody tests, together with an abnormal cholangiogram, he was diagnosed with overlap syndrome (AIH-PSC). Liver imaging revealed innumerable liver masses with a benign appearance in the pathological evaluation. To rule out the colon abnormalities that usually coexist with such liver masses, colonoscopy was performed and showed no significant changes. The liver masses were nonmalignant and were resolved after immunosuppressant therapy.
CONCLUSIONS: Because AIH-PSC overlap syndrome is rare, it is suggested that radiological evaluation of the biliary tree should be performed routinely in adults diagnosed with AIH to reduce the missed diagnosis of overlap syndrome and liver masses.
