Benign focal epilepsy of childhood: epileptic seizure during somatosensory evoked potential: a case report.
A 6-year-old girl with a history of partial seizures had parietal spontaneous spikes, and high-voltage paroxysms, evoked by tapping of the hands and feet, in the parietal contralateral region during the electroencephalogram. The girl underwent a somatosensory evoked potential study, when she had a seizure, with tonic contraction rising of the right leg then followed by clonic jerks of the right leg, version of the head to the right, followed by a tonic contraction of the ipsilateral arm with flexion at the elbow. The seizure lasted 20-30 seconds. We believe this is the first description of a seizure during a somatosensory evoked potential procedure.
