Intracardiac tuberculoma.

We examined a case of endocardial tuberculoma at the proximal superior vena cava and the right atrium in a 17-year-old male patient. He had frequent palpitations and general weakness for about 7 months and was referred for evaluation of incessant atrial tachyarrhythmia. Results of echocardiography and magnetic resonance imaging showed an intracardiac mass, which was excised using cardiopulmonary bypass. Histology of the mass was consistent with the diagnosis of tuberculoma. The patient's postoperative course was uneventful and he was discharged with antituberculous medication. Five months after the operation, the patient was well without tachycardia, and follow-up echocardiography showed complete disappearance of the mass.
