目的对鼻腔部原发性软骨肉瘤的影像学表现进行分析。方法对9例鼻腔部原发性软骨肉瘤患者的影像学征象以及临床表现进行回顾性分析,所有患者中行MRI平扫患者3例,行MRI和CT平扫患者3例,行CT平扫患者3例。扫描完成后由专业影像师进行阅片,评价患者鼻腔肿瘤形状、钙化情况、侵犯范围。结果所有患者经检查确定均为单发,均有不同程度的软组织肿块以及溶骨性骨质破坏。5例患者MRI增强扫描病变边缘分隔明显强化,呈杂乱斑驳样强化2例。结论肿瘤内钙化情况可以通过CT直接显示出来,在鼻腔部软骨肿瘤的鉴别和诊断上具有一定价值;MRI能够直接反映出软组织肿块情况,更加精确、清楚的显示病变范围。CT联合MRI能够更加准确的反应鼻腔部原发性软骨肉瘤情况,在临床上有重要的治疗价值。

Objective To analyze the imaging findings of primary chondrosarcoma in the nasal cavity. Methods Nine cases of primary chondrosarcoma of the nasal cavity were retrospectively analyzed for imaging features and clinical manifestations. All patients underwent MRI plain scan in 3 cases, MRI and CT plain scan in 3 cases, plain CT scan in patients with 3 example. After the scan was read by a professional video division, evaluation of patients with nasal tumor shape, calcification, the scope of violations. Results All patients were confirmed by inspection were single, have varying degrees of soft tissue mass and osteolytic bone destruction. In 5 cases, MRI enhancement enhanced the border of the lesion and obviously enhanced in 2 cases. Conclusion The in-tumor calcification can be directly visualized by CT and has certain value in the diagnosis and differentiation of nasal cartilage tumors. MRI can directly reflect the situation of soft tissue mass and more accurately and clearly show the extent of the lesion. CT combined with MRI can more accurately reflect the nasal cavity of primary chondrosarcoma, clinically important therapeutic value.
