Posterior reversible encephalopathy syndrome in early postpartum woman

There have been reports about posterior reversible encephalopathy syndrome (PRES) associated with pregnancy, especially peripartum. However, the pathophysiology of PRES is not still clear. Tonic-clonic seizure occurred during early postpartum in a woman with the tendency toward pre-eclampsia developed after vaginal delivery followed by emergency cesarean hysterectomy. Postictal findings included headache, loss of vision, and short-term memory loss and magnetic resonance imaging (MRI) findings suggesting PRES were noted. Neurologic symptoms and cerebral lesions were gradually improved with immediate supportive managements. (Hong Kong j.emerg.med. 2012;19:58-61)
