AbstractPosterior reversible encephalopathy syndrome (PRES) is a reversible neurological entity characterized by seizure, headaches, visual symptoms, impaired consciousness and other focal neurological findings. It is caused by a wide variety of causes ultimately leading to a vasogenic cerebral edema of occipital and parietal lobes of the brain. A 10 Year Old Girl presented in Pediatric emergency with altered sensorium and intermittent tonic posturing. During examination her BP was noted to be 140/90mmHg (> 99th percentile for the patient).Urinalysis revealed hematuria. CT Cranium showed prominent ventricles and diffuse hypodensity in cerebellar region. Reversibility of the symptoms after institution of antihypertensivemeasures and MRI brain confirmed the diagnosis of PRES. Post streptococcal Glomerulonephritis (PSGN) was found to be the underlying etiology of PRES.
