Posterior Reversible Encephalopathy Syndrome in Pregnancy

Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiological entity characterized by several symptoms of varied etiologies. The common symptoms are headache, confusion, seizures, cortical visual disturbances or blindness. Here, we report a 22 years old lady with 32 weeks of gestation who presented with complaints of acute onset of headache, sudden loss of vision with elevated blood pressure (BP), whose magnetic resonance venogram (MR venogram) revealed bilateral occipital T2 hyperintensity with restriction of diffusion suggestive of PRES. Early identification and treatment usually results in complete reversal of the deficits and delayed diagnosis and improper management can lead to irreversible sequelae.
