Abstract:
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.
