We report a 37-year-old, right-handed patient with drug-resistant focal epilepsy whose seizures were characterized by explosive hyperkinetic behaviour. Video-SEEG revealed bifocal organization of epilepsy with two distinct cortical origins of seizures: the right temporal pole and left temporal lateral and perisylvian cortex. Irrespective of the cortical pattern of seizure onset, the hyperkinetic semiology was extremely similar. This supports a major role for “final common pathway” subcortical circuits in the genesis of the hyperkinetic semiology in this patient.
