亚急性联合变性颈髓的磁共振成像表现

Subacute Combined Degeneration of the Cervical Spinal Cord: MR Findings

目的分析亚急性联合变性颈髓的磁共振成像表现特点,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,回顾性分析其磁共振成像表现,并复习相关临床及文献资料。结果5例患者磁共振成像均显示颈髓不同程度的后、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例行钆喷替酸葡甲胺增强扫描,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,磁共振成像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）. Methods The findings of MR imaging was retrospectively analyzed in 5 patients with clinic-conformed SCD. The clinical symptoms were also analyzed. Results All five cases demonstrated high signal intensity on T2-weighted images 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 T2-weighted image. Patchy enhancement was noted in 2 cases. Conclusion The characteristic appearance of SCD in cervical spinal cord on MRI is very helpful in diagnosis.
