Role of Electroencephalography in Presurgical Evaluation of Temporal Lobe Epilepsy
Figure 11
(Case 4) (a) Normal EEG in a 20-year-old man with refractory complex partial seizures and right posterior temporal enhancing lesion. (b) Ictal EEG about 30 seconds into one of the typical complex partial seizures shows arrhythmic theta-delta activity over the right temporal-occipital regions. No clear lateralizing ictal EEG changes were discernible early in the seizure (not shown here).
