骨肉瘤是最常见的原发性恶性骨肿瘤,以肿瘤细胞直接形成肿瘤性骨样组织和肿瘤性骨组织为主要特征[1]。由于不同骨肉瘤恶性程度和生长速度存在差异,其影像学表现呈多样化、复杂化的特点[2]。近期,我们对2006—2014年本院收治的骨肉瘤9例的影像学资料进行了回顾性分析,以探讨骨肉瘤的影像学特征,为疾病诊断提供参考依据。现报告如下。1临床资料1.1一般情况本组9例中,男6例,女3例;年龄 Osteosarcoma is the most common primary malignant bone tumor, with tumor cells directly forming tumor-like bone tissue and tumorous bone tissue as the main feature [1]. Due to the difference of malignant degree and growth rate of different osteosarcoma, the imaging features are diversified and complicated [2]. Recently, we retrospectively analyzed the imaging data of 9 cases of osteosarcoma treated in our hospital from 2006 to 2014 in order to explore the imaging features of osteosarcoma and provide reference for disease diagnosis. The report is as follows. 1 Clinical data 1.1 General This group of 9 patients, 6 males and 3 females; age
