ABSTRACT

Posterior Reversible Encephalopathy Syndrome (PRES) was introduced into clinical practice in 1996 in order to describe a syndrome clinically expressed during hypertensive and uremic encephalopathy, eclampsia, sepsis and immunosuppressive therapy. It’s secondary to vasogenic oedema. In the majority of cases changes are localized in posterior irrigation areas of the brain, and in the most severe cases anterior areas is also involved. PRES is a syndrome characterized clinically by headache, confusion, seizures, vomiting, and visual disturbances. CT imaging is typically normal, non-specific or suggestive of PRES or stroke. The classic imaging finding of PRES in MRI are of bilateral parietal and occipital subcortical vasogenic oedema. As the experience with PRES grows, varied and atypical presentations are being described. Therapeutic strategies depend on the cause of PRES. The most important are blood pressure regulation, control of seizures and anti-oedema therapy.
