结果：X线平片清楚显示多中心骨肉瘤病灶， 放射性核素显像骨扫描可见肿瘤灶核素浓集。
Results The multifocal of osteosarcomatosis were clearly depicted by X- ray plain film, and the radionuclide concentration of tumor foci could be seen on radionuclide images.
方法：回顾性分析经手术病理证实的7例骨纤维肉瘤的平片、CT和MRI表现。
Methods: The features of ct and MRI of 7 cases of fibrosarcoma of bone proved pathologically were retrospectively reviewed.
骨肉瘤23例，尤文肉瘤6例，软骨肉瘤2例，侵袭性骨母细胞瘤2例。
There were 23 osteosarcomas, 6 Ewing sarcomas, 2 chondrosarcomas, and 2 invasive osteoblastomas.
骨肉瘤的细胞学诊断与组织学对照符合率为93 4%，骨巨细胞瘤为87 5 %，骨转移性癌为91 6 %。
The diagnostic accuracy rates were 93 4% in osteosarcoma, 87 5% in bone giant cell tumor, 91 6% in bone metastatic carcinoma.
脂肪肉瘤肿块密度不均匀和溶骨性骨质破坏。
The Liposarco-rna always showed inhomogeneous density mass accompanied with lytic bone destruction.
因此我们的研究与先前的研究一致，GNAS的突变在纤维性结构不良中有高度特异性，而在骨旁骨肉瘤和其它低级别骨肉瘤中即使有GNAS突变、也是很少的。
Our findings therefore support prior observations that GNAS mutations are highly specific for fibrous dysplasia and occur rarely, if ever, in parosteal and other low-grade osteosarcomas.
结论骨肉瘤中存在OPG高表达，可能与骨肉瘤的成骨性有关。
Conclusion There was overexpression of OPG in human osteosarcoma. The expression of OPG may have a clo...
