Abstract

Posterior Reversible Encephalopathy Syndrome (PRES) is a clinico-radiological diagnosis characterized by acute or subacute neurological symptoms. A 27-year-old woman at 35 weeks of pregnancy, who presented with generalized tonic-clonic seizures had persistently low Glasgow Coma Scale (GCS) score after delivery of the baby. Magnetic Resonance Imaging (MRI) of the brain showed T-2 Fluid Attenuated Inversion Recovery (FLAIR) hyperintensities in the brainstem, bilateral medial cerebellar hemispheres, bilateral medial temporal lobes, bilateral thalami, lentiform and caudate nuclei, and bilateral fronto-parieto-occipital lobes. There was diffusion restriction in bilateral caudate nuclei, left thalamus and right frontal lobe, and microhemorrhages in the left thalamus. These findings were suggestive of central variant PRES. She improved with strict blood pressure control and anti-edema measures. A repeat MRI brain on day 10 showed significant improvement, and she had no residual neurological deficits. The central variant of PRES is a rare entity that has to be considered in a patient presenting with neurological deficits in the setting of uncontrolled blood pressure, eclampsia, immunomodulatory medication use, or renal failure. While most patients with PRES fully recover with timely therapy targeted at reversing the primary cause, some may have residual neurological deficits or rarely, die.
