title: Acute granulomatous iridocyclitis in a child with tubulointerstitial nephritis and uveitis syndrome.
abstract: BACKGROUND
  Tubulointerstitial nephritis and uveitis [TINU] syndrome is a rare disorder that may also be underdiagnosed. Patients with TINU syndrome typically present with an acute bilateral nongranulomatous anterior uveitis following symptoms of systemic illness.
  
  
  RESULTS
  We report the case of a 15-year-old girl who presented with acute granulomatous iridocyclitis and was diagnosed with TINU syndrome based on renal biopsy findings. Both her uveitis and interstitial nephritis promptly responded to high-dose corticosteroid treatment, and there were no relapses during follow-up of 20 months.
  
  
  CONCLUSIONS
  TINU should be included in the differential diagnosis of patients who present with acute granulomatous uveitis.
