An extensive tumor thrombus is an extremely rare entity in thyroid cancer. It is related to aggressive tumor behavior and a poorer prognosis. 18F-FDG PET is a useful tool for accurate staging and restaging in malignancies as well as the determination of tumor thrombus and its differential diagnosis from benign thromboembolism. We report a rare case of 66-year-old patient with an extensive tumor thrombus in superior vena cava on 18F-FDG PET/CT.
