Clinico-radiological spectrum of obstetric patients with posterior reversible encephalopathy syndrome in a tertiary care hospital
Background: Posterior reversible encephalopathy syndrome (PRES) is a disorder that is not uncommon in pregnancy induced hypertension. We have studied the clinico radiological profile of such patients to understand history, symptomatology and neuro imaging findings of this entity.Methods: The present study included 20 patients of PRES among the inpatients of a tertiary care hospital in south India from January to March 2020.Results: Mean age 25.0 years. Most common symptoms included seizures and headache followed by vomiting, visual disturbances.9 patients (45%) had parieto-occipital signal changes on neuro imaging. Magnetic imaging resonance (MRI) (n=20) revealed involvement of atypical sites viz. frontal (30%), temporal (20%), cerebellum (20%), basal ganglia (20%), deep white matter (30%) and brainstem (10%).Diffusion restriction was seen in 40% patients.Conclusions: Atypical MRI presentations of PRES are common and there is a need to consider a strong possibility for the diagnosis of PRES.
