RENAL ULTRASONIC FINDINGS IN SULFADIAZINE-INDUCED RENAL-FAILURE

The increased incidence of cerebral toxoplasmosis in AIDS has led to a resurgence in the use of sulphadiazine. One complication of this is a cute renal failure secondary to sulphadiazine-induced crystalluria. Th ree cases are described which demonstrate a spectrum of ultrasound fin dings ranging from echogenic foci in the renal parenchyma to echogenic material in both dilated and non-dilated collecting systems. In patie nts with AIDS having sulphadiazine treatment, these ultrasonic finding s suggest that sulphadiazine is the cause of the renal failure.
