探讨增强CT对小儿结核性脑膜炎的临床诊断价值

To Evaluate the Clinical Value of Enhanced CT in the Diagnosis of Tuberculous Meningitis in Children

目的对小儿结核性脑膜炎使用增强CT诊断的临床效果进行分析。方法选取我院2012年1月—2013年1月我院接收的120例小儿结核性脑膜炎患儿作为研究对象,对患儿进行头颅CT和增强CT检查、MRI、CSF等检查。结果 CT结果显示:软脑膜病理性强化占62.5%,脑室系统的扩张及积水占81.7%,脑梗死占11.7%,脑膜结核瘤或脑实质内结核瘤占10.8%,脑萎缩占35.0%。MRI结果显示:检查有效率为95.8%。CSF检查结果中,阳性率为98.3%,同头颅CT增强检查所得的结果相比,差异不具有统计学意义(P>0.05)。结论小儿结核性脑膜炎使用增强CT诊断能够对患儿的病情进行了解,和原有的检查方式进行配合,诊断结果比较客观全面,给临床治疗提供了良好的基础。

Objective To analyze the clinical effect of enhanced CT diagnosis for tuberculous meningitis in children. Methods 120 cases children with tuberculous meningitis received from January 2012 to January 2013 were analyzed with cranial CT and enhanced CT examination, MRI and CSF examinations. Results CT results showed that leptomeningeal pathological enhancement accounted for 62.5%, expansion and hydronephrosis of the ventricular system accounted for 81.7%, accounting for 11.7% of cerebral infarction, meningeal tuberculoma or parenchymal tuberculoma accounted for 10.8% of the total, and brain atrophy accounted for 35.0%. The results of MR1 showed that the effective rate was 95.8%. In CSF examination, the positive rate was 98.3%. Compared with the results of head CT enhancement, the difference was not statistically significant （P 〉 0.05）. Conclusion Children with tuberculous meningitis using enhanced CT diagnosis to children＇s condition to understand, and the original inspection manner, the diagnosis results more objective and comprehensive, which provides a good foundation for clinical treatment.
