摘要
目的:探讨肺滑膜肉瘤(SS)的影像学特点,为临床诊治提供依据。方法:2例原发性肺滑膜肉瘤(PPSS)及13例转移性肺SS患者行胸部CT平扫(或CT增强)检查,观察PPSS和转移性肺SS的CT影像学特征。结果:2例PPSS CT检查显示肺部不均匀密度肿块影,边界清楚,无毛刺,无钙化,增强扫描实质成分明显强化,无肺门和纵隔淋巴结肿大;13例转移性肺SS患者CT表现为大小不等、分布不均的多发或单发结节,边界清楚或模糊,密度均质或不均,部分可见分叶。结论:胸部CT平扫或CT增强检查对早期发现PPSS或转移性肺SS具有一定价值,但对于确诊PPSS和鉴别转移性肺SS仍有困难。
Objective： To investigate the imaging features of pulmonary synovial sarcoma,and provide basis for clinical diagnosis and treatment. Methods： Two cases of primary pulmonary synovial sarcoma（ PPSS） and 13 cases of metastatic pulmonary synovial sarcoma underwent a chest CT scan（ enhanced CT） test,and observing the CT imaging features of primary pulmonary synovial sarcoma and metastatic pulmonary synovial sarcoma. Results： The imaging results of 2 cases of primary pulmonary synovial sarcoma showed uneven density of pulmonary mass,clear boundary,no burr,no calcification,enhanced CT scan showed obvious enhanced components,no hilar and mediastinal lymph nodes enlargement; CT imaging features of 13 cases of pulmonary metastasis synovial sarcoma showed multiple or solitary nodules with different sizes and uneven distribution,clear or vague boundary,homogeneous or uneven,and lobulated change partially visible. Conclusion： The chest CT scan or enhanced CT has certain value to early discovery of the primary pulmonary synovial sarcoma and metastatic pulmonary synovial sarcoma,but it is still difficult in diagnosing the primary pulmonary synovial sarcoma and metastatic pulmonary synovial sarcoma.
