摘要
目的分析成人无骨折脱位颈髓损伤的影像学表现及其临床意义。方法收集该病病人22例,入院时均行颈椎X线、CT及MRI检查。结果 X线及CT上表现为椎管狭窄、椎间盘突出、颈椎生理弧度改变、椎间隙变窄、颈椎不稳、椎体后缘骨赘形成及后纵韧带骨化。颈髓MRI信号改变包括信号无改变6例,脊髓水肿10例,髓内血肿出血6例。结论退变性颈椎管狭窄、颈椎间盘突出等颈椎退变是该病的主要病理基础。MRI信号无改变或仅有水肿表现者预后较好,髓内血肿出血者预后较差。
Objective To analyze the imaging manifestations of cervical cord injury（CCI） without fracture or dislocation of C-spine.Methods Twenty-two patients with CCI without fracture or dislocation of C-spine were enrolled.X-ray,CT and MRI of C-spine were performed on admission.Results On CT and X-ray,the manifestations were spinal stenosis,intervertebral disk hernia,changes of cervical physiological radian,narrowed intervertebral space,cervical instability,vertebral edge hyperplasia,ossification of posterior longitudinal ligament（OPLL）.On MRI imaging of cervical cord,no signal changes were seen in six cases,edema in 10,and intramedullary hemorrhage in six.Conclusion Degenerations of cervical vertebra such as spinal stenosis and prolapse of intervertebral are main pathomechanism of this lesion.The prognosis is good for those with no signal changes or only with spinal cord edema on MRI;the prognosis is poor for those with intramedullary hemorrhage.
