Posterior reversible encephalopathy syndrome (PRES) is a rare clinicoradiologic condition manifesting with headache, seizures, altered sensorium, visual disturbances, and characteristic lesions on neuroimaging predominantly affecting the posterior regions of the brain. We report a case of an 8-year-old boy with poststreptococcal glomerulonephritis, presenting as PRES. A magnetic resonance imaging showed hyperintense lesions in bilateral frontal and parietooccipital parenchyma on fluid-attenuated inversion recovery and T2-weighted images, suggestive of "PRES." Patient made a complete neurological recovery without any deficit.
