摘　　要：目的总结脑电图(EEG)在儿童枕叶癫痫临床诊断及术前致痫灶定位中的作用。方法对17例枕叶癫痫患儿行常规、睡眠EEG描记和头颅CT/MIR检查,结合临床发作症状综合定位致痫灶。结果儿童枕叶癫痫的发作形式有①视觉症状;②运动症状:偏转发作继发全身强直-阵挛发作、偏身抽搐;③复杂部分性发作伴自动症;④发作性呕吐、头痛或偏头痛。脑电图特点:一侧或双侧枕叶或枕叶及周围脑叶出现痫性放电。致痫灶定位于一侧枕叶3例;颞顶枕1例;顶枕1例。5例术后随访,4例无癫痫发作,1例明显好转。结论儿童枕叶癫痫是一组较具特征表现的癫痫综合征。掌握临床表现及脑电图特点,常可做出正确诊断。症状性难治性枕叶癫痫术前定位准确率较高,手术切除致痫灶效果良好。Objective Occipital lobe epilepsy（OLE）in children has not been well known in China ,although many cases have been reported rceently.This study aimed to summarize the importance of electronencephalography（EEG）to the clinical diagnosis and preoperative location of the focal in children with occipital lobe epilepsy.Methods Seventeen patients with OLE were examined to locatize the epilepsy focal with routine EEG,sleeping EEG,CT and MRI.Results The common types of OLE were as follows：①visual symptoms;②motor symtoms：versive sezure;secondarily tonic clonic seizure;hemiclonic seizure;③complex partial seizures with automatism;④ictal vomiting ;headache or migraine.EEG features;discharge over one or both occipital lobe .Five cases were followed up after operation ,4 cases had no seizure ,and the other one got better than before.Conclusions OLE in children is a distinctive epilepsy syndrome.Understanding the clinical manifestations and EEG features can lead to obtain correct diagnosis .Preoperative location is much belpful to the removeal of epilepsy focal in children with symptomatic OLE .
