Renal cell carcinoma presenting as right atrial mass.

Approximately 190 new cases of renal cell carcinoma infiltrate into the inferior vena cava and right atrium every year. Echocardiography often plays a major role in establishing the diagnosis and in guiding surgical therapy. This report describes a patient who presented with shortness of breath but had no classic signs or symptoms of renal cell carcinoma other than chronic anemia. Transthoracic two-dimensional echocardiography and transesophageal echocardiography established the diagnosis of a right atrial mass extending from the inferior vena cava that was later discovered to be renal cell carcinoma.
