Abstract:
Invasive thymoma commonly infiltrates mediastinal structures; however, intracardiac extension from an intracaval growth is rare. An unusual case of an invasive thymoma protruding into the RA is here described. A left brachiocephalic vein (LBCV) tumor appeared through the thymic veins of a 50-year-old female patient. The patient underwent a combined resection of the invasive tumor and superior vena cava (SVC) and right atrium (RA) under cardiopulmonary bypass (CPB). Pathologic examination revealed this to be a WHO type B3 thymoma, Masaoka stage III. Following surgery, the patient's symptoms disappeared, and the quality of life improved. The patient was then introduced to radiotherapy and chemotherapy. This present case indicates that surgical treatment can create the opportunity for radiotherapy and chemotherapy, and is suitable and necessary for the treatment of invasive thymoma.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
