[A solitary intracardiac metastasis in the left atrium from a pulmonary carcinoma].

Cardiac metastases are the most common cause of neoplastic disease of the heart. Usually the metastases involve the pericardium and/or myocardium but rarely they form intracavitary masses. We report a patient with a lung cancer and solitary left atrial intracardiac metastases. General features of cardiac metastases and the differential diagnosis of left intra-atrial masses are discussed.
