Hepatic involvement in Wegener's granulomatosis: a case report

INTRODUCTION: We report the case of a 58-year-old Caucasian Greek man who presented with dry cough, fever, bilateral alveolar infiltrates and acute hepatitis. CASE PRESENTATION: After a lung biopsy, the patient was diagnosed with Wegener's granulomatosis. The diagnosis was supported by the presence of anti-proteinase-3 anti-neutrophil cytoplasmic antibodies. A liver biopsy demonstrated the presence of mild non-specific lobular hepatitis and periodic acid-Schiff positive Lafora-like inclusions in a large number of his liver cells. The patient was treated with prednisone and cyclophosphamide, which was followed by subsequent remissions of chest X-ray findings and liver function studies. CONCLUSION: What makes this case worth reporting is the coexistence of liver inflammation with a biochemical profile of severe anicteric non-viral, non-drug induced hepatitis coinciding with the diagnosis of Wegener's granulomatosis. Our paper may be the first report of hepatic involvement in a patient diagnosed with Wegener's granulomatosis. The aetiological link between the two diseases is supported by the reversion of hepatitis after the immunosuppression of Wegener's granulomatosis. We favor the hypothesis that hepatic vasculitis may be the cause of acute hepatocellular necrosis.
