脑膜瘤的脑电图改变

ELECTROENCEPHALOGRAM CHANGES OF MENINGIOMA

对４２例手术及病理切片证实的脑膜瘤患者行脑电图检查，结果表明：脑电图异常占９５．２４％，其中定位与临床符合率为６４．２９％，定侧符合率为２６．１９％。讨论了脑膜瘤脑电特点及定性诊断价值，认为脑电图仍为一重要的辅助诊断手段。

Electroencephalogram(EEG) was used in investigating 42 cases of meningiomas proved by operations and pathological examinations. The abnormality rate of EEG was 95.24%. Compared with the clinical findings, the accuracy rate of EEG lesion location was 64.29%; the accuracy rate of EEG lesion side location was 26.19%; the total accuracy rate of lesion location and lesion side location was 90.48%. The EEG characteristics and the value of location diagnosis of meningioma were discussed. This indicates that EEG is still an important supplementary diagnostic method of intracranial meningioma.
