脑电图与CT对脑囊虫病的诊断价值

Comparative study of EEG and CT in early youth with cerebral cysticercosis

目的探讨EEG和CT在诊断小儿脑囊虫病中的应用价值。方法对240例小儿脑囊虫病患者的EEG和CT结果进行对比研究。结果该组患者的EEG异常率为86.7%,主要表现为额、中央及前额区弥漫性不规则复型慢波或局灶性慢波。CT异常率为70.8%,主要表现为片状和圆形的低密度灶或高密度灶,两者比较差异有统计学意义(P<0.01)。EEG和CT检查结果符合率为78.8%。结论小儿脑囊虫病患者EEG异常率显著高于CT,临床上两种方法结合起来分别从功能和形态结构上对该病的早期诊断和治疗具有重要的价值。

Objective To investigate the diagnostic value of EEG and CT in early youth with cerebral cysticercosis. Methods The EEG and CT manifestations were studied in 240 early youth with cerebral cysticercosis. Results The abnormal rate of EEG was 86.7 % in children with cysticercosis, which mainly showed the diffuse or focal irregularity complex slow waves in frontal lobe, central lobe and anterior lobe. The abnormal rate of CT was 70.8 % in all patients,and flaky and circular focus were chief manifestations. There was a significant difference between the rates of EEG and CT（P〈 0.01）. The coincident rate of EEG and CT was 78.8 % . Conclusion The abnormality rate of EEG in children with cysticercosis was higher remarkably than that of CT. A combination of the two methods might be helpful for cerebral function and morphogenesis structure in early diagnosis and treatment of children with cysticercosis.
