Variant Type of Posterior Reversible Encephalopathy Syndrome with Diffuse Cerebral White Matter and Brainstem Involvement Associated with Intracranial Hemorrhage

摘要

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome characterized by reversible vasogenic edema typically at a posterior location of the cerebrum. PRES with prominent brainstem or basal ganglia involvement is defined as central-variant, which is rare. We herein report an atypical case of a 35-year-old man with a 2-year history of untreated hypertension who complained of recurrent dizziness. The patient presented with brainstem and diffuse white matter involvement associated with intracranial hemorrhage and recovered fully after therapy. Recognition of this uncommon benign syndrome as a potentially treatable disorder can be of great importance. (C) 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.
