Sulfadiazine-induced nephrolithiasis detected by spiral CT scan.

Abstract

Nephrolithiasis is a known complication of the use of sulfadiazine in the treatment of cerebral toxoplasmosis. Radiographic diagnosis of this complication has historically been challenging. Between March 1999 and June 2002, 11 patients were treated for cerebral toxoplasmosis with sulfadiazine-containing therapy. Four of these patients (36.4%) developed nephrolithiasis during this period. Case patients had received sulfadiazine for a median of 35.5 days prior to nephrolithiasis. All cases were diagnosed by spiral CT scans. Although studies are needed to evaluate the sensitivity and specificity of this modality, spiral CT may aid in the diagnosis of sulfadiazine-induced nephrolithiasis.
