We report a case of hypopharyngeal metastasis of papillary thyroid cancer detected 15 years after subtotal thyroidectomy. CT and MRI showed an enhancing submucosal mass in the hypopharynx with restricted diffusion. The mass was growing slowly. Metastasis of papillary thyroid carcinoma to the hypopharynx is very rare. In all previous case reports, the masses were submucosal or subepithelial. If a submucosal hypopharyngeal mass has a history of papillary thyroid carcinoma, metastasis of papillary thyroid carcinoma should be considered as a differential diagnosis.
