title: Posterior reversible encephalopathy syndrome (PRES).
abstract: Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity. Neurotoxicity with characteristic watershed CT/MR imaging features characterize this  condition. This case report describes PRES syndrome in a 35-year-old patient admitted with eclampsia. On the first postpartum day; she developed severe headache, generalized tonic-clonic seizures and visual symptoms including transient visual loss. MRI scan of the brain showed symmetric areas of hyperintense signal on T2-weighted images in the occipital lobes bilaterally. Patient improved symptomatically. Repeat MRI of the brain 4 months after initial admission showed resolution of the previous abnormalities.
