RADICAL EXCISION OF INVASIVE THYMOMA WITH INTRACARDIAC EXTENSION

A patient with a low grade malignant thymoma who also had pleural, per icardial and cardiac invasion with intracardiac extension, presented w ith signs of superior vena cava obstruction, moderate hepatosplenomega ly and a mediastinal mass on a plain chest radiograph. Radical excisio n requiring cardiopulmonary bypass for the removal of the intracardiac extension into the right atrium was performed. Despite the patient's failure to receive radiotherapy treatment, he was alive one year after surgery. This case is reported because this mode of presentation of i ntracardiac extension of a thymoma is uncommon and because only this m ethod of radical excision could ensure near-total removal of the mass and prevent early death from cardiovascular complications.
