摘　　要：目的总结脊柱骨巨细胞瘤的CT、磁共振成像(MRI)表现,探讨其鉴别诊断。方法分析经病理证实的15例脊柱骨巨细胞瘤的CT及MRI表现特点。结果绝大部分脊柱骨巨细胞瘤病例侵犯多椎体,具有典型特征,表现为偏心性膨胀性骨质破坏,累及单侧附件,形成椎旁软组织肿块,病变以实性成分为主,部分病例见少许囊变区域,个别病例见液-液平面。所有病例均未见骨化、钙化及骨膜反应。结论脊柱骨巨细胞瘤与长管状骨巨细胞瘤均具有偏心性、膨胀性骨质破坏及无骨化、钙化、骨膜反应的特点,但局部形成明显的软组织肿块、多椎体受累的特点与长管状骨巨细胞瘤的表现有别,应予以重视。Objective To summarize the CT and MRI performances of the spinal giant cell tumor and discuss it′s differential diagnosis. Methods Fifteen cases of the spinal giant cell tumor were reviewed and all cases were confirmed by pathology. Results The lesions in majority of the cases perform the typical performances which involve multiple vertebral bodies and are characterized by decentered and expansive fracture damages. The lesios violate one side of the vertebral attachment, forming the soft tissue masess approach to the vertebral bodies. The lesions mainly compose the solid ingredients and some cases come out with partly cystic areas. Several come out with fluid-fluid level and none are with ossification, calcification and periosteal reaction. Conclusion Both the giant cell tumor （GCT） of the spinal and the long tubular bones appear the performances of decentered and expansive fracture damages without ossification, calcification and periosteal reaction. However, the formation of obvious soft tissue masess and the involv-ing of multiple vertebral bodies of the GCT of the spine make it to distinguish from the GCT of the long tubular bones which should be attach importance to.
