Posterior reversible encephalopathy (PRES) is a rare occurrence in patients with Guillain–Barré syndrome (GBS) with only nine adult cases reported to date. We conducted a review of the literature and compared previous cases with a novel case admitted to our clinic. In light of the timing of the symptoms, it is assumable that arterial hypertension can develop acutely during a phase of GBS-related autonomic dysfunction and subsequently precipitates PRES. According to this, dysautonomia caused by GBS could precede motor weakness; thus, PRES in the absence of any strong alternative etiology may suggest an underlying GBS. [ABSTRACT FROM AUTHOR]
