【摘要】 目的:分析脊柱原发性软骨肉瘤的CT和MRI表现,与手术病理结果相对照,提高其影像诊断的准确性。材料与方法:回顾性分析11例经手术病理证实的脊柱原发性软骨肉瘤患者的临床和影像资料,由两位高年资影像医师阅片,对肿瘤的发生部位、侵犯范围、形态、钙化或骨化、强化表现及肿瘤性质进行分析评价。结果:颈椎1例,胸椎7例,骶椎3例。11例均呈溶骨性破坏,4例椎体破坏,5例椎体和附件破坏,2例肋椎关节破坏,11例肿瘤均有软组织肿块形成,8例有明显钙化,4例累及相邻两个椎体。结论:脊柱原发性软骨肉瘤与其它部位软骨肉瘤的CT和MRI表现相似,CT对于钙化的显示具有明显优势,对定性诊断有一定价值,MRI对于显示软组织肿块和椎管内侵犯具有明显优势,对指导临床治疗有重要价值。更多还原

【Abstract】 Objective:To analyze the CT and MRI findings of the primary verbebral chondrosarcoma and correlate with pathology in order to improve the imaging diagnosis.Material and Methods:The clinical and imaging materials of 11 cases with primary chondrosarcoma in spine were analyzed retrospectively.Two radiologists evaluated the localization,erosion,tumormorphology,calcification,enhancement and characteristics of tumor.Results:The location of tumor included cervical spine(n= 1),thoracic spine(n=7),sacral vertebra(n=3).Four cases revealed osteolytic destruction and lesions were originated in vertebral body(n=4),in appendix and vertebra(n=5),in costovertebral joints(n=2).All the tumors with scallop-like soft tissue mass.There were 8 cases with mineralization in tumors.Involvement of adjacent vertebral levels was seen in 4 cases.Conclusion:The CT and MRI findings of the primary chondrosarcoma in spine are similar to the chondrosarcoma happened in other position.Calcification is better delineated by CT,which is helpful to determine the nature of the tumor.MRI is better in delineating the soft tissue neoplasm and vertebral canal encroachment,which is helpful to clinical therapy.更多还原
