摘要
目的:探讨MRI对结核性脊髓脊膜炎的诊断价值。方法:对21例结核性脊髓脊膜炎增强前后的MRI进行回顾性分析。结果:所有21例MRI平扫均可见脊膜受累,主要表现为脊膜不规则增厚,蛛网膜下腔狭窄或闭塞、分隔样改变、囊肿形成,神经根增厚;增强扫描表现为增厚的脊膜呈线状、斑块状、结节状和环状强化。本组21例中脊髓肿胀17例,脊髓空洞6例,髓内结核瘤5例。结论:MRI平扫和增强扫描可清晰显示结核性脊髓脊膜炎的病变部位和累及范围,可为临床治疗及判断预后提供影像学参考。
Objective：To assess the value of MR imaging in the diagnosis of tuberculous myolomeningitis. Methods：The MR imaging findings of plain MR/and contrast-enhanced MRI exanation in all 21 eases with tuberculous myolomeninghis were reviewed retrospectively. Results：Irregular thickened spinal meninges were found in all patients. Non-enhanced MR imaging showed narrowing, oblitera- tion, loculafion or cyst of subaractmoidal space and nerve roots thickening. Abnormally thickened spinal meninges revealed linear, plaque-like, nodular and ring-like enhancement on contrast-enhanced MR images. Spinal cord was involved in all cases, including diffuse spinal cord swelling （17/21）, cavitation （6/21）, and tuberculoma （5/21）. Conclusion： Non-enhanced and contrast-enhanced MR imaging has been found to be useful for delineating the lesion＇ s location and extention of the spinal meninge and spinal cord of tuberculous myolomeningitis. It is of importance in evaluating the selection of therapy and the follow-up therapeutic effect.
