Intrathoracic goiter with hyperthyroidism, tracheal compression, superior vena cava syndrome, and Horner's syndrome

Intrathoracic goiter is an important cause of mediastinal masses. We present a patient with hyperthyroidism, tracheal compression, superior vena cava syndrome (SVCS) and Horner's syndrome due to intrathoracic goiter. To our knowledge, this is the first case in the literature with all of these combined findings.
