We report a case of a left atrial mass echocardiographically mimicking myxoma, in a patient with renal cell carcinoma. The mass was pathologically confirmed to be metastatic carcinoma, which had entered the left atrium from a mediastinal lymph node, via direct invasion of a pulmonary vein, illustrating the potential for unusual routes of tumor spread into the heart and the importance of obtaining a tissue diagnosis in such cases.
