摘要
目的总结骨肉瘤的ＣＴ征象及其特点。方法分析４０例经手术病理证实的骨肉瘤的ＣＴ、Ｘ线平片征象和病理切片。３２例为平扫，８例平扫后行增强扫描。病理检查４０例，其中病理大切片９例。结果骨肉瘤的基本征象有骨质破坏、肿瘤骨形成、骨膜反应及软组织肿块。这些征象在平片、ＣＴ上均可见到，但两者的表现有所不同。ＣＴ还可显示平片不可见或难以发现的征象：肿瘤与周围软组织的分界、肿瘤坏死、出血、肿瘤侵犯关节及跳跃性病灶。增强扫描更有利于显示肿瘤的边界及邻近的血管。结论ＣＴ扩展和加深了我们对骨肉瘤征象的认识，可为临床提供较平片更为准确、全面的影像学信息。
Objective To summarize the CT signs and characteristics of osteosarcoma. Methods The CT and plain film signs and pathological sections of 40 cases of osteosarcoma were analyzed. 32 cases had only plain CT scans, while 8 cases had both plain and enhanced CT scans. All cases had pathological sections, 9 also had macro sections. Results The basic signs of osteosarcoma were bone destruction, tumor bone formation, periosteal reaction, and soft tissue mass, which could be demonstrated by both plain film and CT scan, although there were some different features between them. CT could also demonstrate some findings not revealed on plain film, such as the boundary between tumor and surrounding soft tissue, necrosis and bleeding, joint invasion by tumor, and skip lesions. Enhanced CT scans were advantageous in showing the tumor border and neighboring vessels. Conclusions CT expanded and deepened our understanding about the signs of osteosarcoma, and provided much more accurate and comprehensive imaging informations than plain film.
