Reversible posterior leukoencephalopathy in a child with acute glomerulonephritis follow up MR imaging

Abstract

Hypertensive encephalopathy is the most common cause of reversible posterior leukoencephalopathy syndrome, which is quite rare in the pediatric age group. Diffuse vasogenic edema in the posterior circulation territories at the initial stages and complete disappearance of edema on follow-up imaging is the characteristic feature of this syndrome. Frontal and temporal lobe involvement is rarely seen. In this report we present the follow-up MR and diffusion weighted imaging findings of reversible posterior leukoencephalopathy syndrome in a pediatric case with this rare involvement in addition to characteristic involvement localization.
