亚急性联合变性颈髓的MRI表现

MRI findings of subacute combined degeneration of the cervical spinal cord

目的:分析亚急性联合变性颈髓的MRI表现特点,提高对该病的认识。方法:收集临床确诊亚急性联合变性累及颈髓的患者5例,回顾性分析其MRI表现,并复习相关临床及文献资料。结果:5例患者MRI均显示颈髓不同程度范围的后蛐和侧索长T2信号,其颈髓正中矢状位T2加权图像均呈连续束带状异常信号;4例行Gd-DTPA增强扫描,其中2例可见条片状强化。结论:亚急性联合变性的颈髓矢状位束带状改变有比较典型的特点,MRI是诊断该病的重要手段。

Objective： To analyse the MR manifestations of subacute combined degeneration of the cervical spinal cord （SCD）, and to improve the understanding of SCD. Methods： The findings of MBI were analyzed retrospectively in 5 patients with clinically confu＇med SCD. The clinical symptoms were also analyzed. Results： All five cases demonstrated high signal intensity on T2WI in the posterior and/or lateral column of the cervical spinal cord, and ribbon-like high signal intensity along dorsal aspect of the cervical spinal cord on sagittal T2WL Patchy enhancement were noted in 2 cases. Conclusion： The characteristic appearance of SCD in cervical spinal cord on MPd is very helpful in diagnosis.
