A Rare Presentation of Posterior Reversible Encephalopathy Syndrome in Recovery Phase of Guillain-Barré Syndrome.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological syndrome, in which a patient presents with neurological symptoms, including headache, seizures, altered sensorium, and loss of vision, and accompanied with characteristic magnetic resonance imaging findings which are likely to be reversible. Guillain-Barré syndrome (GBS) is an acute demyelinating polyneuropathy presumably related to immunological mechanisms. Here, we describe a patient who had PRES in recovery phase of GBS while he was neither on any immunomodulator nor was having hypertension. He recovered completely clinically as well as radiologically.
