目的 分析儿童枕叶癫的临床和脑电图特点及其临床意义。方法 对 5 2例枕叶癫患儿的临床和脑电图资料进行分析并对部分患儿进行随访。结果 5 2例患儿中 ,男 2 8例 ,女 2 4例 ;首发年龄 2个月～ 12岁 ,平均 5岁 8个月 ;<1岁 5例 ,～ 3岁 8例 ,～ 7岁 31例 ,>7岁 8例 ;对其中 2 8例进行随访 ,包括脑电图、头颅CT及核磁共振成像 (MRI)等。枕叶癫常见的发作形式有 :(1)枕叶起源的症状即视觉发作症状占 2 9% (15 5 2 ) ,偏转发作占 2 9% (15 5 2 ) ,发作性呕吐占 19%(10 5 2 ) ,头痛或偏头痛占 2 3 % (12 5 2 ) (2 )发作扩散到其他部位引起的症状即迅速转化的全身性大发作占 5 0 % (2 6 5 2 ) ,意识障碍占 2 7% (14 5 2 ) ,单侧肢体抽动占 12 % (6 5 2 ) ,躯体及口咽喉自动症占 8%(4 5 2 ) ,失神占 6 % (3 5 2 ) ,唾液过多占 4% (2 5 2 )。发作间期脑电图表现为枕叶反复出现高幅节律性棘慢波或尖慢波发放 ,闭眼时出现 ,睁眼时消失。结论 枕叶癫为一组较为特征性的综合征 ,临床表现多样化 ,尤应重视视觉发作症状及脑电图发作间期枕叶异常放电的特点。
Objective To analyze the clinical and electroencephalographic characteristics of children with occipital lobe epilepsy and its clinical significance. Methods Clinical and electroencephalographic data of 52 children with occipital lobe epilepsy were analyzed and some of them were followed up. Results Among 52 cases, 28 were males and 24 were females; the initial age ranged from 2 months to 12 years, with an average of 5 years and 8 months; 5 cases were <1 years old, 8 cases were ~ 3 years old and ~ 7 years old were 31 years old Cases,> 7 years old in 8 cases; of which 28 cases were followed up, including electroencephalography, cranial CT and magnetic resonance imaging (MRI). Occurrence of occipital lobe epilepsy common forms are: (1) occipital lobe symptoms that visual symptoms of 29% (1552), deflection accounted for 29% (1552), vomiting accounted for 19% (10 5 2), headache or migraine headache accounted for 23% (12 5 2) (2) the symptoms spread to other parts of the attack caused rapid conversion of the generalized major attack accounted for 50% (2652), awareness Barriers accounted for 27% (14 5 2), unilateral limbs twitch accounted for 12% (65 2), somatic and oropharyngeal larynx accounted for 8% (452), absences accounted for 6% (3 5 2), saliva Too much 4% (2 5 2). Seizure interval EEG showed occipital lobe repeated high amplitude rhythmic spikes slow or sharp wave release, closed eyes, eyes disappear. Conclusion Occipital lobe epilepsy is a group of more characteristic syndromes with diversified clinical manifestations, especially the symptoms of visual attack and the abnormal discharge of occipital lobe during the episode of electroencephalography.
