A case report on papillary carcinoma thyroid with intraorbital and intracranial metastasis

Papillary thyroid cancer (PTC) is the most prevalent form of differentiated thyroid cancer (DTC), typically confined to the neck and often leading to remission. Although distant metastases in DTC are uncommon, they usually involve the lungs and bones, with the liver and kidneys being less frequently affected. Metastasis to intra-orbital and intracranial sites is exceedingly rare. We hereby present a case of 68-year-old woman who presented with proptosis of right eye and swelling in right side of neck since 15 years. Fine needle aspiration cytology of both the thyroid swelling and orbital mass was done, which revealed papillary carcinoma thyroid and metastatic orbital deposits.
