Reversible Encephalopathy

Posterior reversible encephalopathy syndrome (PRES), previously known as hypertensive encephalopathy, is a clinicoradiologic entity manifesting as acute onset of headache, encephalopathy, seizures, and vision abnormalities. The characteristic clinical features and predominantly posterior cerebral edema were first described by Hinchey and colleagues in 1996. Since then, many conditions have been associated with PRES.

Introduction: Posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS) might represent a pathophysiological spectrum. They are commonly diagnosed separately, based on prominent clinical features. We aimed to compare clinical and radiographic findings of PRES and RCVS. Methods: We performed a retrospective study of adult patients admitted to a tertiary medical center from February 2008 until February 2018 and were diagnosed with PRES or RCVS. Patient demographics, risk factors, clinical features, imaging, and outcomes were compared. Appropriate statistical tests were used to compare the variables and significant findings are reported. Results: There were 281 PRES and 98 RCVS cases meeting diagnostic criteria. Seizures, encephalopathy, and hypertension were more common with PRES, whereas headache was more common with RCVS (p <0.001). Hypertension and transplant recipient or immunocompromised status were associated with PRES (p <0.001), as did diabetes mellitus (p <0.05). Marijuana use, smoking, and obesity were associated with RCVS (p <0.05). ). Intraparenchymal or subarachnoid hemorrhage was found in 51 PRES cases and 34 RCVS cases. Arterial stenosis was present in 19 % of PRES cases. Brain FLAIR MRI hyperintensity that was reversible on follow-up was present in 26% of RCVS cases. Conclusion: PRES and RCVS share common clinical characteristics and might represent a pathophysiological spectrum, though distinct clinical features were noted in our retrospective analysis.
