200例颅内结核CT影像学临床特征探讨

200 cases of intracranial tuberculosis CT imaging clinical features to explore

目的:观察颅内结核患者的CT影像学临床特征。方法:抽取某医院200例颅内结核患者参与本研究,对200例患者实施颅内结核CT扫描诊断,观察200例患者的CT影像学临床特征。结果:200例患者头颅CT平扫均可发现不同程度的异常,阳性率为67.5%,增强扫描后,可见脑膜、脑血管、脑实质发生病变,阳性率为97.0%。根据CT扫描结果诊断出结核性脑炎患者70例,结核性脑膜炎患者86例,结核性血管炎患者32例,结核瘤患者12例,诊断准确率为97.5%,与病理诊断结果比较差异无统计学意义(P>0.05)。结论:颅内结核患者的CT影像学缺乏典型性,临床诊断时应重视对患者头颅增强CT扫描结果的观察和分析,以提高患者的临床诊断准确率。

Objective：To observe the CT imaging of clinical characteristics of patients with intracranial tuberculosis.Method：extract from May 2012 to May 2015 treated 200 cases of intracranial tuberculosis patients to participate in this study, for 200 cases of patients with intracranial CT scan in the diagnosis of tuberculosis, observe 200 cases of CT imaging clinical features.Results：200 cases of head CT scan can be found in patients with various degrees of abnormal, positive rate was 67.5%, the enhancement scan, visible meninges, cerebrovascular and parenchymal lesions, positive rate was 97.0%. According to the results of CT diagnosis of tuberculous encephalitis patients 70 cases, 86 patients with tuberculous meningitis,32 patients with tuberculous vasculitis, 12 patients with tuberculoma, diagnostic accuracy was 97.5%, compared with the pathological diagnosis has no obvious difference （P〉 0.05）.Conclusion：The CT imaging of intracranial tuberculosis patients lack of representativeness, should pay attention to when the clinical diagnosis of patients with head enhancement CT scanning results of observation and analysis, in order to improve the accuracy of clinical diagnosis of patients.
