目的：探讨EEG、MR对颞叶癫 (TLE)术前定位。方法：用MR、EEG对20例TLE病例进行术前定位与术中EEG和术后随访结果比较。结果：20例病例中17例依据MR及EEG获得定位，主要在海马区域病变12例，前颞叶5例，另3例MR检查正常，依据多次EEG检查获得定位，随访疗效满意。结论：EEG是诊断TLE的重要手段，MR可对继发性TLE作出正确诊断，MR对海马硬化检查可协助EEG对TLE定位诊断。,Aim:To discuss pre-operative localization of epileptic foci in intractable temporal epilepsy by EEG and MR. Meth-ods: MR and EEG were used to localize the epileptic foci in 20 patients with intractable temporal lobe epilepsy (TLE)pre-oper-atively,all the patients had intra-operative cortical EEG examination and post-operative follow-up. Restults: 17 patients’ seizurefoci were localized by MR and EEG examination ,among them l 0 patients have hippocampus sclerosis, 3 cases tephromalacia, 2cases arachnoid cyst, 1 case glioma. Another 3 cases were localized hy repetitive EEG examinaticm while MR examinationswere normal. All patients were followed up after operation,the result was satisfactory. Conclusion:EEG is the most importantlocalizing method for temporal lobe epilepsy,MR is useful for the secondary TLE．Examination of hippocampus for HS will behelpful while the ordinary MR examination is normal.
