We examined a 56-year-old man who presented with dyspnea and lower extremity edema. A 2-D echocardiogram showed a large mass within the right ventricle which spared the right atrium and the inferior vena cava. Pathologic evaluation identified a renal cell carcinoma with sarcomatoid features. The tumor had metastasized to and invaded the right ventricular myocardium without right atrial or caval involvement. This pattern of metastases is rare and suggests that this tumor's aggressive nature contributed to the degree of myocardial invasion as well as the patient's rapid demise.
我们检查了一名56岁男性，他出现了呼吸困难和下肢水肿。二维超声心动图显示右心室内有一个大肿块，未累及右心房和下腔静脉。病理评估确定为具有肉瘤样特征的肾细胞癌。肿瘤已转移并侵犯右心室心肌，未累及右心房或腔静脉。这种转移模式很罕见，表明该肿瘤的侵袭性导致了心肌侵犯程度以及患者的快速死亡。
