Posterior reversible encephalopathy syndrome is a radiological and clinical syndrome which is rarely seen in children. Hypertensive encephalopathy, renal failure, treatment with immunsuppressive agents, retansion of fluid, eclampsia, and transfusion are among the main etiological causes. In this report, we present the initial diagnostic and follow-up MR imaging findings of a 7 years old girl, who had been followed with chronic renal failure for 4 years, admitted to our pediatric department with symptoms of seizure and hypertensive episode, and diagnosed as having posterior reversible encephalopathy. On follow-up MR imaging, hemorrhage, a possible complication of this syndrome, was developed. Posterior reversible encephalopathy should be considered in the differential diagnosis of hypertensive children with seizures, and cranial MR and diffusion weighted MR imaging should be routinely performed in these patients.
