Abstract

Abstract Posterior reversible encephalopathy syndrome (PRES) is a reversible neurological entity characterized by seizures, headache, visual symptoms and other focal neurological findings. It is caused by wide variety of causes ultimately leading to vasogenic cerebral edema of occipital and parietal lobes of the brain. Prompt and early diagnosis of PRES is key in reducing the risk of permanent neurological sequelae. Occurrence of PRES during pregnancy or early postpartum period is well known. However, occurrence of PRES between 48 hours and one month postpartum in women who had normal pregnancy and delivery and no signs of preeclampsia is rare. In this case series we present three cases of PRES that occurred in young women during late postpartum period. All these three patients were normotensive during antenatal and early puerperal period but developed hypertension and vision loss in late puerperium. The prompt diagnosis and management of symptoms resulted in complete reversal of the symptoms with no permanent neurological deficit. Posterior reversible encephalopathy syndrome (PRES) is a reversible neurological entity characterized by the presence of white matter edema affecting the occipital and parietal lobes. The predominantly affected area of the cerebral cortex determines presentation in the patient. The reversibility of these symptoms is one of the hallmarks of the disease. Diffusion-weighted MRI is the gold standard in diagnosis of PRES as it helps to distinguish between vasogenic edema from cytotoxic edema. Prompt diagnosis and initiation of early treatment may lead to complete recovery with no residual neurological deficit.
