Posterior reversible encephalopathy syndrome with neurological sequelae - a case report

Posterior reversible encephalopathy syndrome (PRES) is a set of neurological symptoms including impaired consciousness, cognitive disorders, seizures, blurred vision, dizziness and headache. The symptoms are closely related to the location of pathological changes in the brain; bilateral occipitto-parietal region is most often affected. Both focal neurological symptoms and encephalopathy are usually transient. We present the case of 64-year-old woman with PRES. She suffered from many internal diseases and was admitted to the hospital due to impaired consciousness, speech disorders, balance disorders. Significant neurological deterioration was observed within several days from the onset. Differential diagnosis included stroke and viral neuroinfection (cytosis 23 cells /ul, protein level of 93 mg/dl); magnetic resonance examination revealed lesions typical for posterior reversible encephalopathy.After 6 weeks of hospitalization patient condition improved, but did not restore to the premorbid state. The patient was discharged with generalized cognitive impairment.
