摘　　要：目的　分析骶骨原发性肿瘤的X线和CT表现。方法　回顾性分析经临床手术病理证实的 10例骶骨原发性肿瘤 ,其中脊索瘤 5例 ,骨巨细胞瘤 2例 ,软骨肉瘤 2例 ,神经鞘瘤 1例。结果　 (1)脊索瘤常累及S3～ 5,有中央性肿块 ,平片与CT为溶骨性骨质破坏 ,瘤内有残余骨嵴和钙化 ;(2 )骨巨细胞瘤常累及S1～ 3,呈膨胀性骨质破坏 ,好发于青年人 ;(3 )软骨肉瘤 ,神经鞘瘤X线和CT上各有特点。本组 1例软骨肉瘤从S1～ 3骨质破坏 ,并向盆腔内长出一巨大肿块。结论　X线平片与CT结合 。Objective To analyse the X-ray and CT manifestations of sacral primary tumor.Methods 10 cases with sacral primary tumors verified by pathology,including sacral chordoma(n=5),giant cell tumor(n=2),chondrosarcoma(n=2),neurilemmomas(n=1),were analysed retrospectively.Results (1)The manifestations of CT and X-ray of sacral chordoma presented as a midline destructive lesion,involving prominently at sacrum 3～5,with flocculent calcification and irregular bone crests.(2)Giant cell tumor involved predominately sacrum 1～3 with expansile destructive area and commonly in young adults.(3)Chondrosarcoma and neurilemmomas had difference characteristic on X-ray film and CT.One case with chondrosarcoma had bone destruction in sacrum 1～3 and giant mass grow into pelvis.Conclusion CT combined with X-ray film is helpful in diagnosis and differential diagnosis of sacral primary tumors.
