Asymptomatic posterior reversible encephalopathy syndrome-like brain MRI in a case of Guillain-Barré syndrome

Background: Posterior reversible encephalopathy syndrome (PRES) was first reported in 1996 and consists of a reversible vasogenic oedema predominating in the cerebral posterior white matter. There are several known causes of PRES, including hypertension and intravenous immunoglobulin (IVIg) therapy. We report the case of an asymptomatic PRES during the course of a Guillain-Barre syndrome (GBS).
