脑结核的CT诊断

CT Diagnosis in Tuberculosis of the Brain

为了探讨脑结核的CT诊断 ,对经临床综合诊断的 95例脑结核的CT结果进行回顾性分析 .结果 :CT对脑结核的检出率为 80 % .脑结核CT直接征象为脑池渗出、脑膜强化、脑实质结核 .间接征象有脑积水、脑梗塞、脑内钙化、脑室旁低密度、脑萎缩、脑软化和硬膜下积液 .最常见的CT表现为脑积水 ,其次为脑池渗出、脑膜强化和脑梗塞 ,其它则少见 .结果表明 :(1)对两种直接征象同时出现或一种直接征象加上两种以上的间接征象一起出现时可得出脑结核的诊断 ;(2 )脑结核CT扫描应常规平扫加增强 .

To evaluate CT in the diagnosis of tuber culosis of the brain. CT findings in 95 cases with tuberculosis of the bran confirmed clinically were analyzed retrospectively. Results: The CT detectability fate was 80%. The direct CT sings included exudation in basal system, meningitis, enhancement and intracranial tuberculosis.
