Ectopic thyroid is an abnormal thyroid gland embryogenesis; the thyroid is not in the normal position of the neck but appears in other parts. About 90% of the ectopic thyroid is located at the base of the tongue. This case showed a mass in the right supraclavicular region, which initially diagnosed as metastatic Lymph Node (LN) on CT and MRI in a nasopharyngeal carcinoma patient. While, this mass had no FDG uptake through 18F-FDG PET/CT imaging, and it was a finally confirmed as ectopic thyroid tissue pathologically using needle biopsy. We emphasis the important role of 18F-FDG PET/CT for confirming and excluding lymph node metastasis.
