Acute renal failure due to acute tubulointerstitial nephritis.

Acute interstitial nephritis (AIN) should be ruled out in children with unexplained acute renal failure. We present a 4 1/2 year old girl who presented with oliguric acute renal failure preceded by a febrile illness. Renal histopathology revealed features of drug induced AIN. She recovered with dialysis, other supportive treatment and a course of steroids.
