%X Tumors that metastasize to paranasal sinus (PNS) are rare, with fewer than 200 cases reported worldwide. Of these, thyroid malignancies contribute 8%. We discuss here a patient aged 45 years with PNS mets from follicular variant of papillary carcinoma thyroid who had undergone surgery and radioiodine ablation. He presented with nasal obstruction and epistaxis 2 years after local treatment. CT scan of PNS showed a large heterogeneously enhancing mass lesion in PNS, which on further evaluation was found to be consistent with metastases from primary thyroid cancer. He was given palliative radiotherapy to the metastatic lesion. Patient was alive after eighteen months of radiotherapy but there was no response to radiotherapy on imaging. To conclude PNS metastases from thyroid cancer are rare. But it should be always kept in mind in symptomatic patients. Also, patients with PNS mets can have a long disease free survival after palliative radiotherapy.
