Posterior Reversible Encephalopathy Syndrome (PRES) is a neuroradiologic diagnosis, first described in 1996 by Hinchey et al. (1), consisting of haedache, seizure s, altered mental status and a specırum of visual deficits ranging from visual neglect to corlical blindness. It is of ten related to an acute increase in arterial blood pressure, is clinically indistinguishable from hypertensive encephalopalhy, and has been associated with preeclampsia, renal failure, and hypercalcemia (2). Although imaging modalities demonstrate generally hypodensities, usually of the posterior white and grey matter; the temporal and frontal lobes, brainstem and cerebellum may be involved (2,3).
