Figure 2

18F-FDG-PET of a 73-year-old man with an 8-year history of papillary thyroid carcinoma. The serum thyroglobulin was elevated at 66 ug/L (normal < 55 ug/L), but both diagnostic whole-body 131I scan and ultrasound were negative for recurrence. (a) FDG-PET revealed hypermetabolic uptakes in left cervical lymph node, right thyroid bed, and right sternoclavicular joint area. (b) An operative picture confirming the presence of tumor recurrence at the right thyroid bed (as pointed by the tip of the forceps).
