结核性脑膜炎的CT诊断(附16例分析)

目的：通过分析16例结核性脑膜炎的CT表现及其产生的病理基础，提高对本病的认识和诊断水平。方法：16例结核性脑膜炎病人采用常规头颅CT扫描，对其影像及临床资料进行回顾性分析。结果：脑基底池、侧裂池变窄12例(75％)，合并密度增高8例(50％)；不同程度的脑积水14例(88％)；脑梗塞8例(50％)；结核瘤1例(6％)。结论：结核性脑膜炎的主要CT征象是脑基底池、侧裂池变窄，同时有不同程度的脑积水。如同时伴有脑结核瘤，可作出诊断。

jective: To analyse CT manifestations and pathologic features of tubercles meningitis, and to improve the cognition and diagnosis of the disease. Methods: Normal CT scans were performed in sixteen cases of tubercles meningitis. The CT images and clinical data were reviewed retrospectively. Results: The brain basal cistern and sylvian narrow were observed in 12 cases (75 % ) ; the density increased in 8 cases( 50% ) , various degrees of hydrocephalus were found in 14 cases( 85 % ) , cerebral infarcts in 8 cases (50%), and tuberculomas in 1 case(6% ) . Conclusion: The main CT manifestations of the tubercle meningitis are basal cistern sylvian narrow and various degrees of hydrocephalus. CT can also make diagnosis of cerebral tuberculomas if there is.
