目的探讨脊髓脊膜结核的MRI表现及MRI对其诊断价值。方法回顾性分析8例脊髓脊膜结核影像表现,所有病例均行MRI平扫和增强检查。结果8例脊髓脊膜结核中,3例为脊髓结核,2例为脊髓脊膜结核,3例为脊膜结核。脊髓结核表现为脊髓内结核性肉芽肿(2例)、粟粒性结核(1例)和结核性脊髓炎(2例)。MRI平扫表现为脊髓肿胀,长T1、长T2信号;增强分别表现为环状强化、粟粒性结节和不强化。脊膜结核MRI表现为脊膜广泛增厚,蛛网膜下腔变窄、闭塞,MRI增强典型表现为“管状(矢状位)”或“环状(横切位)”强化。所有病例均伴有邻近其它脏器或组织的活动性结核病变。结论脊髓脊膜结核MRI表现典型,结合病史,邻近脏器和组织结核病变可以明确诊断。
Objective To investigate the MRI findings of spinal meningococcal tuberculosis and their diagnostic value. Methods Eight cases of spinal tuberculosis were retrospectively analyzed. All patients underwent plain MRI and enhanced MRI. Results 8 cases of spinal meningococcal tuberculosis, 3 cases of spinal tuberculosis, 2 cases of spinal tuberculosis, 3 cases of spinal tuberculosis. Spinal tuberculosis showed tuberculous granuloma in the spinal cord (2 cases), miliary tuberculosis (1 case) and tuberculous myelitis (2 cases). MRI showed the swelling of the spinal cord, long T1, long T2 signal; enhancement showed annular enhancement, miliary nodules and not enhanced. Spinal tuberculosis MRI showed extensive extensive mediastinal, subarachnoid narrowing, occlusion, MRI enhancement is typically manifested as “tubular (sagittal) ” or “ring (transverse position) ” enhancement. All cases were accompanied by active tuberculosis adjacent to other organs or tissues. Conclusions MRI manifestations of spinal cord tuberculosis are typical. Combined with medical history, the adjacent organs and tissues of tuberculosis can be diagnosed clearly.
