A persistent focal abnormality was observed in 157 (16%) electroencephalograms undertaken in 964 consecutive children with epileptic and non-epileptic seizures seen over one year. CT head scans were performed in 121 (77%) of the 157 children with a focus on the EEG; 26 (21%) showed an abnormality, and 21 (81%) of the abnormalities were localised. There was no difference in the proportion of abnormal scans associated with a delta or slow wave focus compared with a spike or sharp wave focus. An abnormal scan was uncommon after a single seizure. In only two patients (1.7% of all scans) did the findings on CT alter or greatly influence subsequent management.
在连续一年中诊治的964例患有癫痫性和非癫痫性发作的儿童进行的157份脑电图检查(16%)中观察到持续性局灶性异常。对157例脑电图有病灶的儿童中的121例(77%)进行了头部CT扫描;26例(21%)显示异常,其中21例(81%)异常病灶得以定位。与尖波或锐波灶相比,与δ波或慢波灶相关的异常扫描比例没有差异。单次发作后出现异常扫描的情况并不常见。仅在两名患者中(占所有扫描的1.7%),CT检查结果改变或极大地影响了后续治疗。
