Role of Electroencephalography in Presurgical Evaluation of Temporal Lobe Epilepsy
Figure 15
(Case 6) EEG in a 38-year-old woman with refractory complex partial seizures and left MTS. (a) Background EEG that showed mild independent bilateral temporal and generalized slowing; (b) right anterior temporal spikes (*); (c) left anterior temporal spikes (**) (right temporal IEDs to left temporal IEDs 70 : 30) in sleep; (d) left temporal type 2 ictal rhythm as rhythmic delta activity in the left temporal regions (arrows) during one of her typical complex partial seizures (seizure onset zone). A total of 16 seizures were captured from the left temporal region. She underwent a left ATL and was seizure-free at last followup 12 months and had a marked reduction in the right temporal IEDs.
