Multimodality treatment with surgery, radioiodine therapy and targeted therapies are used for management of tumor thrombus associated with thyroid malignancies, though no established guidelines exist. Authors present a woman of post-operative follicular thyroid carcinoma (FTC) thyroid with tracer avid tumor thrombus in right brachiocephalic vein, treated with 131-iodine (131I) as a single modality for both remnant and tumor thrombus. Her subsequent follow-ups revealed excellent response to treatment. ER -
