摘　　要：目的：分析颈椎脊索瘤的 X线、CT和 MRI影像学特点,提高本病的诊断水平。方法收集经手术病理证实的7例颈椎脊索瘤患者的 X线、CT和 MRI的影像学资料并对其进行回顾性分析。7例患者均行 X线、CT检查,3例行 MRI检查。结果X线检查：7例椎体呈骨质破坏,1例椎体结构塌陷,6例累及邻近椎间隙并致其变窄,3例周围见软组织肿块。CT检查：7例椎体呈溶骨性骨质破坏,2例见钙化及残骨组织,5例肿瘤累及椎附件及横突孔,4例周围见软组织肿块。3例行 MRI 检查：T1 WI 呈等信号3例,T2 WI呈高低混杂信号3例。3例周围见软组织肿块。结论颈椎脊索瘤较为少见,应充分分析影像学特点,对提高诊断、指导临床手术治疗及预后有重要的意义。Objective To analyze the X-ray,CT and MRI findings of chordoma in the cervical vertebrae,so as to improve its diagnostic accu-racy.Methods X-ray,CT and MRI findings of 7 cases of chordoma proved pathologically were analyzed retrospectively.X-ray and CT were undergone in all 7 cases,MRI in 3 cases.Results X-ray demonstrated bony destruction in 7 cases,bony collapse in 1 case. Narrowing of inter-vertebral space was in 6 cases and soft tissue mass was in 3 cases.CT demonstrated bony destruction in 7 cases, calcification within the tumors in 2 cases,involvement of the accessory of the cervical vertebra and transverse foramen in 5 cases. Soft tissue mass was around the cervical vertebra in 4 cases.MRI was undergone in 3 cases.On T1 WI middle signal in 3 cases were showed,on T2 WI low and high mixed signal in 3 cases,and soft tissue masses around the lesion in 3 cases.Conclusion Chordoma of the cervical vertebrae is uncommon.Full understanding X-ray,CT,MRI characteristics is useful to improve the diagnosis,guide clinical surgery treatment and forecast prognosis.
