We report a case of microscopic polyangitis presenting with acute pericarditis. A 75-year-old man, who had recurrent acute pericarditis, was referred by a cardiologist because of bilateral infiltrates in the chest radiograph, microhematuria and progressive renal failure. The test for MPO-ANCA was positive. Transbronchial and renal biopsies were compatible with microscopic polyangitis, showing alveolar hemorrhage and crescentic glomerulonephritis. After 3 days, intravenous methylpredonisolone was given, followed by oral prednisolone 40 mg/day, and the patient's radiographic infiltrates cleared and renal dysfunction improved. However, he died from opportunistic infection 109 days after the onset of treatment. |
