title: Metastases in the sphenoidal sinus in a patient with papillary thyroid cancer.
abstract: Tumours that produce metastases in the paranasal sinuses or sphenoidal sinus are rare; the carcinomas of kidney and lung being the most frequent with this type of metastasis. Distant metastases from differentiated thyroid carcinoma are rare and, moreover, when they metastasize, they do so into lung and bone. We report a patient who had a papillary thyroid carcinoma with metastases into the sphenoidal sinus.
