Abstract:
Objective To investigate the morphological difference of spinal single vertebral tuberculosis and metastasis by means of CT.Methods CT features of 16 cases of single vertebral tuberculosis and 17 cases of single vertebral metastasis which were proven by clinically and/or pathology, were retrospectively analyzed,and then the CT differential criteria of the two categories of diseases was recommended.Results The reliable CT findings for vertebral tuberculosis were as follows: involvement of anteriomedial potion of vatebral body,presence of sequstra in lesion ,marginal sclerosis in the edge of lesion,calcification within paravertebralmass or abscesses ,only edge enhancement of more of paravertebralmass.Metastasis was characterized by involvement of posteriomedial portion of vertebral bone,absence of sequestra within lesion ,no calcification within paravertebralmass.Both of them had normal intervertebral disc.Conclusion The different CT features of the single vertebral tuberculosis and metastasis are helpful in differerntiating diagnosis ,the morphological change of intervertebral discs is not helpful in differerntiating diagnosis .
