Extension of metastatic lung tumors into the left atrium via pulmonary veins is rare. Here, we report the first case of Ewing sarcoma exhibiting such extension. A 31-year-old man with pulmonary metastasis from Ewing sarcoma presented with a mass in the left lung, extending to the left atrium through the left inferior pulmonary vein. As the patient was considered to be at risk of tumor embolism, the mass was excised surgically.
转移性肺肿瘤经肺静脉延伸至左心房的情况较为罕见。在此，我们报告首例出现这种延伸情况的尤因肉瘤病例。一名31岁的男性，患有尤因肉瘤肺转移，表现为左肺有一肿块，经左下肺静脉延伸至左心房。由于该患者被认为有肿瘤栓塞风险，遂通过手术切除了肿块。
