摘　　要：目的　分析脊柱溶骨性转移瘤的CT表现 ,探讨CT对该病的诊断及鉴别诊断价值。方法　分析 46例 72个椎骨溶骨性转移瘤的CT表现 ,并与其中 2 8例的X线平片结果进行比较。结果　 46例脊柱溶骨性转移瘤的 72个转移椎骨中 ,椎体破坏 45例共 74个病灶 ,椎弓根破坏 2 2例 ,累及横突 15例 ,椎板和棘突 (受累 )各 11例。微转移病灶集中在椎体 ( 4 5 /4 9)。CT发现骨破坏、椎管受累及椎旁软组织肿块分别为 10 0 %、67.85 %及 71.4% ,而X线对三者的发现率仅为 5 3 .6%、14 .3 %及 3 2 .1%。结论　脊柱转移瘤首先侵犯椎体 ,椎体转移瘤是椎弓根、椎板、横突和棘突破坏的基础。Objective To study CT value of diagnosis and identified diagnosis in osteolytic metastases of the vertebral column through describing their CT manifestation.Methods In 46 patients, 72 vertebrae osteolytic metastases were analyzed and compared with X-ray findings of 28 cases.Results In 72 vertebrae osteolytic metastases, there were destruction of 74 corpus vertebrae in 45 patients, of pediculus arcus vertebraes in 22 cases, of processus transverses in 15 cases, of processus spinosus in 11 cases and lamina vertebrae in 11 cases. Micrometastases were concentrated in corpus vertebrae(45/49). CT found the rate of bone-destruction, affection of vertebrae canal and soft tissue around vertebrae were 100%, 67.8% and 71.4%, but the corresponding rates were only 53.6%, 14.3% and 32.1% by X-ray. Conclusion Vertebral column metastases destructed corpus vertebrae at first, vertebral metastases are the origin or base of destruction of the pediculus arcus vertebrae, lamina vertebrae, processus transverses and processus spinous. CT scanning is more sensitive in finding and evaluating the lesions than X-ray plain film.
