摘　　要：目的分析创伤后脊髓空洞症的MRI表现及其形成机制。方法回顾性分析31例脊髓损伤后发生脊髓空洞症病例,MRI重点观察脊髓及其空洞的形态和信号特征。结果31例患者累及脊髓颈段11例、颈胸段6例、胸段4例、胸腰段5例、全脊髓5例、延髓5例、脑桥1例。T1加权像为脑脊液样低信号;T2加权像呈均匀或不均匀高信号。23例患者可见脊髓、蛛网膜、硬脊膜粘连、外伤后栓系改变。结论MRI不但能反映创伤后脊髓空洞症的特点,还能描述蛛网膜硬脊膜粘连范围、程度,对指导手术有益。Objective To analyze MRI manifestations of post-traumatic syringomyelia and its formation mechanism.Methods A retrospective analysis of the clinical data of 31 patients with post-traumatic syringomyelia was carried out.Morphous and signal features of spinal cord and syringomyelia was observed by MRI.Results Among 31 patients,11 cases had syrinx extending to cervical cord,6 cases extending to cervicothoracic cord,4 cases extending to thoracic cord,5 cases extending to thoracolumbar cord,5 cases extending to whole spinal cord.5 cases of 31 patients had syrinx ascending to medulla oblongata,1 cases ascending to pons.The post-traumatic syringomyelia had signal intensities similar to cerebrospinal fluid on T1-weighted sequences and uniformed or ununiformed signals of increased intensity on T2-weighted sequences.23 cases of all patients can demonstrate adhesion and traumatic tethering by MRI.Conclusion MRI can not only demonstrate the characteristics of post-traumatic syringomyelia but also describe the range of spinal cord,arachnoid and dura mater adhesions,which is of value in deciding how to perform operations.
