为了探讨颅脑损伤后癫痫的法医学鉴定要点，对21例颅脑损伤后癫痫出现发作者进行了现病史、既往史调查，并结合临床脑电图（EEG）及X线片、CT片、MRI片等影像学资料。结果发现外伤后癫痫常继发于严重的颅脑损伤，多以晚期发作为主，其发作性质决定于颅脑损伤的部位和程度，头皮EEG和24小时动态EEG证实有异常癫痫样波存在，影像学检查有助于定性分析。结果提示：外伤性癫痫法医学鉴定必须以掌握外伤史及既往史为基础，结合EEG、CT、MRI等检查方可作出正确鉴定。%To evaluate the forensic determination of post cerebral traumatic epilepsy. Methods In 21 patients, traumatic history and previous history were analysied combined with the demonstrations of electroencephalogram(EEG), X-ray, CT and MRI. Results Post-traumatic epilepsy,manily in late stage, usually occurred following serious cerebral trauma. The type of traumatic epilepsy was determined by the traumatic location and extent. Abnormal epileptic wave in scalp EEG and 24h dynamic EEG and medical image examinations were helpful for qualitative analysis. Conclusion The forensic determination of post traumatic epilepsy must be on the basis of traumatic and previous history combined with EEG, CT and MRI analysis.
