The authors report a 27-year-old woman with a remote left femoral osteosarcoma and amputation above the left knee who presented with a large right ventricular mass. Initial evaluation with thoracic CT was inconclusive regarding thrombus versus tumor, but metastatic osteosarcoma was suggested by findings at transthoracic echocardiography, cardiac CT, and cardiac MRI. The patient underwent tumor debulking, and osteosarcoma was confirmed with pathologic examination. She responded to chemotherapy, which resulted in reduction in size of the residual right ventricular tumor and of a few pulmonary metastases. Following induction chemotherapy, patient remains well undergoing maintenance therapy with an oral tyrosine kinase inhibitor.

作者报告了一名27岁女性，既往有左股骨骨肉瘤病史且左膝以上截肢，现出现右心室巨大肿块。胸部CT的初步评估对于血栓与肿瘤的鉴别尚无定论，但经胸超声心动图、心脏CT和心脏MRI的检查结果提示为转移性骨肉瘤。患者接受了肿瘤减瘤手术，病理检查确诊为骨肉瘤。她对化疗有反应，化疗导致残余右心室肿瘤和一些肺转移灶的大小缩小。诱导化疗后，患者情况良好，正在接受口服酪氨酸激酶抑制剂的维持治疗。CT、超声心动图、磁共振成像、术中、心脏、心脏、右心室、成像序列、转移、肿瘤学 © RSNA，2021年
