Abstract

It is very rare for papillary thyroid cancer metastasize to nasopharynx. We report FDG PET/CT findings of a solitary nasopharyngeal metastasis from papillary thyroid cancer 4 decades after the initial diagnosis in a 66-year-old woman, which mimics nasopharyngeal carcinoma. The final diagnosis was confirmed by pathological examination from the biopsy of nasopharyngeal lesion.
