CT and MRI findings of the chordoma in the mobile spine / 实用放射学杂志

ABSTRACT

Objective To study the CT and MRI features of the chordoma in the mobile spine.Methods The CT and MRI fea-tures were retrospectively analyzed in twenty-four cases of chordoma in the mobile spine.Results In all the twenty-four cases,bone lesions were solitary in eight cases and multiple in sixteen cases,mostly occurred in cervical,occasionally occurred in thoracic or lum-bar vertebra.Both vertebral body and part appendix were involved in all cases.CT imaging showed that all the lesions mainly mani-fested as osteolytic bone destruction,peripheral osteosclerosis and the cortical bone were incomplete.Soft-tissue mass involved para-vertebral and intraspinal.Five lesions appeared vertebrae compression.Eight lesions appeared intervertebral foramen expansion.Le-sions appeared honeycomb or annular enhancement after contrast media injection.Lesions were presented as heterogeneous slightly hypo-isointensity on T1 WI,hyperintensity on T2 WI.Low signal fibrous septa within the tumors were seen.Lesions appeared hon-eycomb enhancement after Gd-DTPA injection.Conclusion CT and MRI findings of chordoma in the mobile spine can be regarded as characteristic,which are helpful for clinical diagnosis.
