Rasmussen’s Encephalitis: A Report of a Moroccan Pediatric Case

Rasmussen's encephalitis (RE) is a rare progressive inflammatory disease of the central nervous system. It is characterized by unilateral hemispheric atrophy, pharmacoresistant focal seizures, and progressive neurological deficit. The exact etiopathogenesis still remains unknown. Brain imaging plays an important role in diagnosis and follow-up. Fluctuation of lesions in brain imaging was reported in few cases. We report the case of a 12-year-old boy initially with intellectual development disorders presented to the pediatric emergency department with complaints of multiple episodes of seizures resistant to treatment.
