This case highlights that nonischemic cardiomyopathy can be a rare initial manifestation of advanced renal cell carcinoma, which may improve following tumor resection.

May indicate reversible paraneoplastic cardiomyopathy after renal tumor resection; hypothesis-generating and requires prospective confirmation before clinical consideration.
We report the rare case of a patient with advanced renal cell carcinoma (RCC) who initially presented to the hospital with symptoms of cardiac failure. Preoperative cardiac studies did not reveal any underlying ischemia. After resection of a large 14-cm left renal tumor, cardiac function was noted to improve dramatically. We discuss this case of concomitant RCC and nonischemic cardiomyopathy.
