摘要
本资料表明，神经胶质瘤的脑电图阳性率高于脑膜瘤的脑电图阳性率，颅盖部脑膜瘤的脑电图阳性率高于颅底部和中线部位的阳性率。脑膜瘤血运愈丰富，其脑电图的阳性率愈高，神经胶质瘤病理级别愈低（恶性程度愈低）准确定位率愈高，病理级别愈高（恶性程度愈高）弥散性异常的机率愈大；病程短而脑电图即为弥散异常者，恶性度可能大。这一研究表明：结合病史和脑电图的改变，脑电图的检查对颅内占位性病变，不仅可作为定位诊断的手段，对定性诊断也有着重要的参考价值。
Abstract It was found that EEG positivity rate of glioma was higher than that of meningioma,and that of meningioma of the skullcap was higher than those of the base and the median line of the skull.The richer the blood supply of meningioma .the higher the positivity rate.The lower the pathological grade of glioma,the higher the accuracy of its location.and the higherthe grade,the greater the diffusion. When the course ofthe disease was short but EEG showed an abnormaldiffusion,the probability of malignancy was greater.
