[A case report of giant mediastinal thyroid carcinoma with SVC syndrome].

A 78-year-old man with SVC syndrome caused from compression by follicular carcinoma of the thyroid which extended to the mediastinum was presented. CT and MRI demonstrated a giant right thyroid tumor which extended to the mediastinum and displaced the trachea. The resection of 675 g-tumor was performed through median sternotomy and right collar incision without reconstruction of SVC. His postoperative course was complicated with recurrent nerve paralysis which had been gradually improved for several months. At present, he has been freed from SVC syndrome.
