Posterior reversible encephalopathy syndrome in a 5-year-old boy with steroid-dependent nephrotic syndrome.

Posterior reversible encephalopathy syndrome (PRES) is a rare clinical and radiological phenomenon is encountered in children compared to adults. In our center, a 5-yearold boy with steroid-dependent nephrotic syndrome (SDNS) presented with headache and blurring of vision during relapse after a long course of immunosuppressive therapy. Evaluation by computed tomography scan of the brain showed that the child had hypodense areas throughout the occipital region of the brain. All signs of PRES, except papilledema, resolved after seven days of supportive treatment evidenced by subsequent radiological evaluation. PRES should be kept in mind in any nephrotic child who is on prolonged immunosuppressive therapy.
