Abstract:

　A 46-year-old manpresented with fever, bilateral pulmonary nodular infiltrates　for 3 month, and oliguric renal failure for 15 days. The urine　analysis revealed proteinuria and haematuria, and PR3-ANCAs were positive detected by ELISA. He complained of a sharp pain with sudden onset in his right side, and a drop in haemoglobin developed in the subsequent hours. Abdominal CT scan revealed a large right-sided perinephric haematoma. A selective arterial angiography showed　multiple impressive aneurysms in renal arteries, active bleeding was present in right. The final diagnosis was granulomatosis with polyangiitis and rupture of renal arterial aneurysm.

Key words: granulomatosis with polyangiitis, renal aneurysm
