case_images: The patient was born to a Jewish (Eastern European ancestry) father and a Japanese mother ( Figure 1A ). Tests for hepatitis B and C virus were negative. 18F-fluorodeoxyglucose positron emission tomography with computed tomography scanning demonstrated fluorodeoxyglucose accumulation in the cervical lymph nodes and right knee joint ( Figures 1B, C ). Moreover, magnetic resonance imaging revealed contrast enhancement along the synovium of the right knee joint ( Figure 1D ). Figure 1E ). Fortunately, his condition improved with conservative treatment.

case_images: AIH was not clear, the overall histopathological image was consistent with that of AIH ( Figures 2A, B ). According to the revised original scoring system of the International Autoimmune Hepatitis Group, our patient had a score of 14 prior to treatment, indicating a probable diagnosis of AIH.
