脑瘤患者的脑电图都有不同程度的改变。因此,应用脑电图检查对大脑半球肿瘤的定位及定侧诊断有一定的作用。现将我院1975年3月～1981年1月经手术和病理证实的54例大脑半球肿瘤患者的脑电图改变分析如下。资料与方法54例中,男性37例,女性17例。年龄1～10岁4例,11～20岁12例,21～30岁8例,31～40岁13例,41～50岁10例,51岁以上7例。肿瘤的部位、大小、性质均经手术证实,详见表1和表2 EEG brain tumor patients have varying degrees of change. Therefore, the application of electroencephalography on the location of the brain hemisphere tumor and definite diagnosis of a certain role. Now in our hospital from March 1975 to January 1981 by surgery and pathology confirmed 54 patients with cerebral hemispheres of EEG changes are analyzed as follows. Materials and Methods 54 cases, 37 males and 17 females. There were 4 cases aged from 1 to 10 years, 12 cases from 11 to 20 years old, 8 cases from 21 to 30 years old, 13 cases from 31 to 40 years old, 10 cases from 41 to 50 years old and 7 cases over 51 years old. The tumor site, size, nature were confirmed by surgery, as shown in Table 1 and Table 2
