Treatment Approach to Follicular Thyroid Carcinoma Tumor Thrombus in the Internal Jugular Vein and Brachiocephalic Vein

Abstract

Thyroid gland carcinoma causing tumor thrombus in the great veins of the neck and mediastinum is a rare condition with poor prognosis. Invasion of the internal jugular vein by thyroid gland carcinoma has been occasionally reported, but tumor thrombi extending to the great veins of the mediastinum are reported extremely rarely. We present a treatment approach in a case of follicular thyroid carcinoma intravascular tumor thrombus in the left internal jugular and left brachiocephalic vein.
