摘要
本文报道了６７例中枢神经系统结核的ＣＴ及ＭＲＩ表现，其中结核性脑膜炎３８例，脑结核瘤１８例，结核性脑膜炎合并结核瘤５例、合并脊髓蛛网膜炎６例。头颅ＣＴ对病变显示率为８４．６％，病损类型有基底池渗出物、脑积水、结核瘤、脑梗塞、脑萎缩及基底池钙化等。增强ＣＴ扫描应列为常规检查。４例结核性脊髓蛛网膜炎ＭＲＩ扫描，显示蛛网膜下腔闭塞消失、髓内外结核瘤、脊髓受压或肿胀及晚期空洞形成，此类影像表现既往国内文献无系统报道。ＣＴ及ＭＲＩ各有长短。
CT and MRI findings in 67 cases with CNS tuberculosis were reported. There were 38 tuberculous meningitis, 18 brain tuberculomas, 5 tuberculous meningitis combined with tuberculoma and 6 with spinal cord arachnoiditis. Abnormal CT findings were shown in 84.6%, including basal cistern exudation, hydrocephalus, tuberculoma, cerebral infarction, brain atrophy, basal cistern calcification, etc. Enhanced CT scan should be done. 4 cases of spinal cord arachnoiditis using MRI examination showed obliteration of subarachnoid space, tuberculoma inside or outside the spinal cord, swelling of the cord and cavity formation. The authors discussed the value of CT and MRI.
