Synonym: posterior reversible encephalopathy syndrome (PRES)
Reversible posterior leukoencephalopathy syndrome presents with rapid onset of symptoms including headache, seizures, altered consciousness and visual disturbance. It is often but not always associated with acute hypertension. If promptly recognised and treated, the clinical syndrome usually resolves within a week and the changes seen in magnetic resonance imaging (MRI) resolve over days to weeks.1
