119例癫痫病CT分析

A Retrospective Analysis of CT Features of 119 Cases of Epilepsy

本文对119例癫痫病CT片回顾分析,评估CT、EEG及常规X线检查的价值,探讨癫痫的病因。提出:癫痫诊断中,CT与EEG结合能明显提高阳性率,减少漏诊和误诊。尤其对临床疑有额、顶、颞叶病变更适于CT检查。早发与迟发性癫痫的区别有较重要的意义,前者以良性病变多见,预后好,但临床缺乏明显定位体征;后者以肿瘤和血管性疾病多见,预后差,多数有定位体征,应重视早期CT检查,以便及时处理。本文还发现,早发性癫痫以继发性多见。

In order to assess the diagnostic value of CT,EEG and conventional radiography and to probe the etiology of epilepsy,the CT films and relative materials of 119 cases of epilepsy were analyzed retrospectively.It was found that the combined examination of CT and EEG could significantly increase the accuracy of diagnosis and minimize the chances of misdiagnosis.CT was especially useful to examine those cases clinically suspected to have lesions in the frontal,parietal or temporal lobe.CT was also important to distinguish the cases of early epilepsy from those of delayed one.Early epilepsy usually resulted from benign lesions with good prognosis but lacked localization signs clinically.Delayed epilepsy mostly is caused by neoplastic or vascular lesinos with poor prognosis,and localization signs were usually present.Prompt CT examination would be helpful in its management.It was also found that early epilepsy was mostly secondary in nature.
