[Mercaptoacetyltriglycine renal scan for the differential diagnosis of acute tubular necrosis and interstitial nephritis associated to vancomycin].

The differential diagnosis of vancomycin associated renal toxicity includes acute tubular necrosis and interstitial nephritis. We report a case of vancomycin induced renal toxicity shown by Tc-99m mercaptoacetyltriglycine renal scan. Nephrotoxicity was evolved secondary to vancomycin used for treating a patient with meningitis. Tc-99m mercaptoacetyltriglycine renal scan may play a role in differentiation between acute tubular necrosis and tubulointerstitial nephritis of vancomycin associated renal toxicity and can facilitate the clinical decision making.
