The MRI diagnosis of spinal tuberculosis in 11 patients
-
摘要: 目的：探讨MRI诊断脊柱结核的价值。方法：回顾性分析经手术病理检查或穿刺活检证实的11例脊柱结核患者的MRI影像资料,观察脊柱结核的MRI信号改变。结果:单椎体受累2例,2个椎体受累4例,3个及3个以上椎体受累5例。11例均见椎体骨质破坏,表现为虫蚀状,其中6例出现跳跃病灶,T1加权像(T1WI)均呈低信号,T2WI呈高信号;椎间盘破坏3例,表现为椎间盘变形,失去正常结构,在T1WI均呈低信号,T2WI呈不均匀高信号,受累椎间隙狭窄。寒性脓肿4例,T1WI多呈低信号,T2WI均表现为明显高信号,增强扫描为不规则及环形强化。结论：MRI对脊柱结核具有较高的诊断价值,尤其利于发现多部位脊柱结核。Abstract: Objective: To explore the value of MRI in the diagnosis of spinal tuberculosis. Methods: The MRI data of 11 patients with spinal tuberculosis diagnosed by operation pathology and paracentesis biopsy were retrospectively analyzed. The MRI signal of spinal tuberculosis was observed.Results: Single vertebral body lesion in 1 case， two vertebral bodies lesion in 2 cases，3 or more than 3 vertebral bodies lesion in 5 cases were found. Bone destruction of all cases were found，bone destruction of vertebral body showed worm bite shape'， jumping lesion in 6 cases were found， the signal of T1 weighted imaging(T1WI) and T2WI were low and high，respectively. The intervertebral disc destruction in 3 cases were found，which showed intervertebral disc deform and losing normal structure， the signal of T1WI and T2WI were low and uneven high， respectively， the involved intervertebral space was narrow. Cold abscess in 4 cases were found， the signal of T1WI and T2WI were low and obviously high， respectively， the enhancement scan wasirregular or ring-shape reinforcement. Conclusions: MRI has high diagnostic value for spinal tuberculosis， especially for multi-part spinal tuberculosis.
