We present a rare case of a mediastinal liposarcoma concomitant with aortic insufficiency due to myxoid degeneration of the aortic valve. Because the patient's left ventricle was in moderate dilatation and a posterolateral thoracotomy combined with median sternotomy was required in order to perform a complete resection of a mediastinal liposarcoma, it was decided to carry out aortic valve surgery and tumor excision in one operation.
