A Reversible Posterior Encephalopathy Syndrome Caused by Eclampsia

The clinical and radiological presentation described in patients with diff erent pathological conditions, such as hypertensive encephalopathy, eclampsia, uremia, use of immunosuppressives and porphyria, represents a syndrome called PRES, or a reversible posterior encephalopathy syndrome. We report two patients with PRES due to eclampsia, aiming to draw attention of clinicians and radiologist to the existence of this clinical and radiological entity. When early recognized and adequately treated, PRES may be reversible, otherwise permanent neurological sequelae are likely.
