Deskripsi

Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen. Renal histology revealed granulomatous interstitial nephritis with necrotizing vasculitis. Outcome was favorable after the institution of high dose corticosteroids along with cyclophosphamide. Renal involvement is rare in sarcoidosis. However, the diagnostic delay should be avoided to improve the outcome.
