目的:探讨颌骨骨肉瘤的影像学特征,提高对该病的诊断与鉴别诊断能力。材料与方法:回顾性分析14例经手术与病理证实的原发颌骨骨肉瘤的X线平片、CT表现。结果:颌骨骨肉瘤影像学表现包括骨质破坏、骨膜反应、软组织肿块,部分病例可见肿瘤骨和肿瘤钙化。X线平片诊断最佳,CT检查有助于鉴别诊断。结论:颌骨骨肉瘤影像结合临床综合分析定性不难。
Objective: To investigate the imaging features of osteosarcoma of the jaw to improve its ability of diagnosis and differential diagnosis. Materials and Methods: X-ray and CT findings of 14 cases of primary osteosarcoma confirmed by surgery and pathology were retrospectively analyzed. Results: The imaging features of osteosarcoma of the jaw include bone destruction, periosteal reaction and soft tissue mass. In some cases, tumor bone and tumor calcification can be seen. X-ray diagnosis of the best, CT examination can help differential diagnosis. Conclusion: The diagnosis of osteosarcoma in the jaw combined with clinical comprehensive analysis is not difficult.
