我们报道了 3 例因手术结果判断为颞叶引起的医学上难治性复杂部分性癫痫发作 (CPS) 的患者，其中头皮脑电图 (EEG) 显示额极区有发作性癫痫样放电。所有患者的头颅磁共振成像（MRI）、正电子发射断层扫描（PET）和发作期单光子发射计算机断层扫描（SPECT）结果与颞叶癫痫（TLE）一致。通过 2 名患者的慢性硬膜下记录，确定了颞叶的致癫痫区域。经过手术治疗（分别是杏仁核海马切除术、颞前叶切除术和颞叶病灶切除术），所有 3 名患者均不再癫痫发作，头皮脑电图上的发作间期额极癫痫样放电消失。 TLE 患者可能会出现发作性头皮脑电图，并伴有额极发作。这很可能是通过我们的一名患者癫痫样放电的偶极方向来解释的； 2. 发作活动快速蔓延至额极区也可考虑。
We report 3 patients with medically intractable complex partial seizures (CPS) arising from the temporal lobe judged by surgical outcome, in whom scalp electroencephalogram (EEG) showed ictal epileptiform discharges at the frontopolar region. In all patients, results of cranial magnetic resonance imaging (MRI), positron emission tomography (PET), and ictal single photon emission computed tomography (SPECT) were consistent with those of temporal lobe epilepsy (TLE). The epileptogenic area was defined in the temporal lobe by chronic subdural recording in 2 patients. After surgical treatment (amygdalohippocampectomy, anterior temporal lobectomy, and temporal lesionectomy, respectively), all 3 patients became seizure-free and the interictal frontopolar epileptiform discharges on scalp EEG disappeared. Patients with TLE may show ictal scalp EEG with frontopolar onset. This is most likely explained by direction of dipolar orientation of epileptiform discharges in 1 of our patients; rapid spread of ictal activity to the frontopolar area can also be considered in the 2.
