Case Report/Case Series

Epilepsy is very rarely attributed to posterior reversible encephalopathy syndrome (PRES). We report the case of a previously healthy 21-year-old who developed epilepsy with mesial temporal sclerosis following an episode of PRES related to a complicated Cesarean delivery. Neuroimaging at the time of PRES and 3 months after revealed the development of unilateral hippocampal volume loss following resolution of acute PRES-related brain edema. We discuss the incidence and importance of “non-reversible” sequelae of PRES and their implications for patient care.
