%X El S¨ªndrome de Encefalopat¨ªa Posterior Reversible (PRES) es una entidad descrita en 1996 que ocurre en pacientes con condiciones sist¨¦micas complejas, especialmente embarazadas con pre-eclampsia, en que se agregan signos y s¨ªntomas neurol¨®gicos destacando convulsiones t¨®nico-cl¨®nicas, cefalea, trastornos visuales y v¨®mitos acompa ados de edema cerebral posterior transitorio visible con t¨¦cnicas de neuro-im¨¢genes y localizado m¨¢s frecuentemente en lobulos parietales y occipital. Presentamos dos casos cl¨ªnicos con PRES y Eclampsia, antenatal y postparto, en las que despu¨¦s del episodio convulsivo con Resonancia Nuclear Magnetica se confirm¨® imagen de edema cerebral propia de PRES y que en relaci¨®n con tratamiento anti-convulsivante e hipotensor, tuvieron una evoluci¨®n favorable. Se discuten la controversia de mecanismos fisiopatol¨®gicos, las posibilidades para diagn¨®stico y manejo oportunos y la importancia del manejo multidisciplinario. The Posterior Reversible Encephalopathy Syndrome is a neurological condition described on 1996, developed in patients with complex systemic conditions, especially pregnant women with preeclampsia that at the same time presented neurological signs as seizures, headache, visual loss, and vomiting in addition to posterior brain edema, visible on neuroimaging and located in parietal and occipital lobes, that usually reverses completely. We present two clinical cases with PRES and eclampsia, antenatal and post-partum, both with seizure and confirmed brain edema with Nuclear Magnetic Resonance. Both had a favorable evolution after the anticonvulsivant and anti-hypertensive therapy were done. We discuss the controversy over pathophysiolgical mechanisms, the new methods for diagnosis and management and the importance of multidisciplinary approach.
