The authors report the case of a patient with a large mass in the right ventricle which was a tuberculoma without pulmonary disease. The severity of the right ventricular obstruction required surgical intervention with quadri-antitubercular therapy. Myocardial tuberculomas are very rare and usually reported as post-mortem findings. Only four cases resulting in cure have been previously reported. Current means of investigation such as echocardiography and endomyocardial biopsy allow rapid diagnosis of these tumours and should lead to better medical management with possible surgical intervention and a higher therapeutic success rate.
