Is poor outcome predictable in posterior reversible encephalopathy syndrome? A case series

Abstract

Posterior reversible encephalopathy syndrome (PRES) was first described by Hinchey et al. in 1996, as a distinct clinico-radiological disease with clinically presence of acute onset seizures, encephalopathy, headache and/or visual disturbances together with radiological findings of vasogenic brain edema typically in the parieto-occipital white matter.1,2 The prognosis of PRES is generally benign. However, it can result in poor outcome and even death.3-5 We aimed to analyze the clinical findings of PRES patients followed at our institution and identify the possible unfavorable prognostic factors. We retrospectively reviewed the hospital charts of patients diagnosed with PRES in the last two years.
