Reports a rare case of renal cell carcinoma metastasis to the left atrium via the inferior pulmonary vein, successfully treated with surgical resection.
May support feasibility of bypass-assisted resection in rare cardiac metastases; leaves open generalizability and long-term outcomes.
Cardiac involvement by intravascular protruding renal cell carcinoma is a well-recognised phenomenon. It most commonly occurs through inferior vena cava extension. Here, we report a case of a lower lobar lung metastasis from renal cell carcinoma involving the left atrium via the inferior pulmonary vein in a patient presenting with von Hippel-Lindau disease. Complete surgical resection was achieved under cardiopulmonary bypass.
