目的:探讨毛细血管扩张型骨肉瘤的影像表现和鉴别,提高对毛细血管扩张型骨肉瘤的影像学认识。方法:结合文献资料,对毛细血管扩张型骨肉瘤的影像表现和鉴别诊断进行分析。结果:毛细血管扩张型骨肉瘤表现为溶骨性膨胀性骨破坏,病变区内多发囊变及液-液平面,CT、MRI增强可见囊壁明显强化,需与动脉瘤样骨囊肿及骨巨细胞瘤进行鉴别。结论:毛细血管扩张型骨肉瘤影像表现异于其他亚型骨肉瘤而与良性膨胀性生长的骨肿瘤类似,影像结合临床及病理特点可提高诊断正确率。
Objective: To investigate the imaging manifestations and differential diagnosis of telangiectasic osteosarcoma and to improve the imaging knowledge of telangiectasic osteosarcoma. Methods: According to the literature, the imaging manifestations and differential diagnosis of telangiectasid osteosarcoma were analyzed. Results: Tumescent dilated osteosarcoma showed osteolytic expansion of bone destruction, multiple cystic lesions and liquid-liquid level in the area. The enhancement of CT and MRI showed that the cyst wall was obviously strengthened, and aneurysmal bone cyst and bone giant Cell tumor identification. Conclusions: The imaging characteristics of telangiectasic osteosarcoma are different from those of other subtype of osteosarcoma, which is similar to that of benign and malignant bone tumor. The imaging combined with clinical and pathological features can improve the diagnosis accuracy.
