Abstract:

A 50-year-old man was submitted to total thyroidectomy due to a rapid growing thyroid nodule (Bethesda III).Histopathology revealed an anaplastic thyroid carcinoma, extending into the adjacent skeletal muscular tissue and with vascular invasion. The patient developed left internal jugular vein thrombosis at the postoperative period.His staging ¹⁸F-FDG PET/CT showed a neoplastic thrombus in the left superior thyroid vein extending into the left internal jugular vein. Another thrombus was noted in the left brachycephalic vein, extending into the superior vena cava.The ¹⁸F-FDG PET/CT were crucial for staging and altering patient management from surgery to chemo/radiation therapy.
