Methods: Observational retrospective study of MS patients evaluated at a single MS reference center in Buenos Aires, Argentina, between 2011 and 2022, focusing on those who developed epilepsy (EMS).

Purpose: Neurosurgery appears to be a reasonable alternative in carefully selected patients with refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE).

Methods: We identified 3 patients (two pediatric and one adult) who underwent epilepsy surgery because of RSE or SRSE from our epilepsy surgery database, one of them with previous SEEG.
