Posterior-reversible-encephalopathy syndrome and antepartum eclampsia.

PRES is a cliniconeuroradiologic entity in which the patient presents with headache, altered mentation, seizures, cortical blindness, and rarely focal neurologic signs. On imaging in majority of cases, characteristic changes suggestive of edema are noted in the posterior irrigation area of the brain. One of the differential diagnoses of PRES in pregnancy and postpartum period is cortical venous thrombosis [1]. Our case is a primigravida at 35 weeks of pregnancy with antepartum eclampsia, cortical blindness, and PRES, who responded favorably to treatment.
