Follicular thyroid cancers are known to spread hematogenously to the bones and lungs and rarely presenting with massive angioinvasion. We report a case of a middle-aged female who had undergone total thyroidectomy for minimally invasive follicular thyroid cancer with angioinvasion in 2014. She was noted to have a large tumor thrombus extending from the superior vena cava to the right atrium on whole body scan post-Iodine-131 (131I) remnant ablation therapy. We discuss the various imaging modalities, treatment options, and difficulties in managing such massive angioinvasion in patients with well-differentiated thyroid cancers.
