Resection of bilateral occipital lobe lesions during a single operation as a treatment for bilateral occipital lobe epilepsy

Figure 2 Clinical findings in a 15-year-old male patient with bilateral occipital lobe epilepsy. A: Scalp video-electroencephalography (EEG) recordings demonstrated abnormal discharges in the right occipital region during the interictal period; B and C: magnetic resonance imaging (MRI) revealed abnormal signals in the bilateral occipital lobe; D: T2-FLAIR MRI showed irregular high signals in the bilateral occipital lobe that suggested ischemic changes; E: A subdural grid electrode was placed during surgery under general anesthesia; F: Anteroposterior and lateral head X-rays (taken after closure of the craniotomy) showing the position of the subdural grid electrode; G-I: Representative EEG recordings made using the subdural grid electrode showing abnormal discharges arising from both sides of the occipital lobe; The upper half of each trace shows recordings obtained from the left occipital lobe, and the lower half of each trace shows recordings obtained from the right occipital lobe; J: Postoperative cranial computed tomography.
