Calvarial metastasis from papillary thyroid carcinoma: A case report

A large variety of metastatic tumors can be found in the skull; breast, prostate, lung carcinoma, multiple myeloma, neuroblastoma and sarcoma are among those that have been reported in the literature. in the current case, a very rare case of metastasis to skull from papillary thyroid carcinoma is reported. a 45-year-old man was admitted to our service with head trauma. computed tomography and magnetic resonance imaging revealed lytic mass lesions in the right frontal and occipital bone extending through the dura mater and subcutaneous tissue. right frontal, suboccipital craniectomy, tumor excision were performed and microscopic examination revealed papillary thyroid carcinoma metastasis. there is no consensus on treatment protocols for patients with central nervous system metastases from papillary thyroid carcinoma, most likely because of the rarity of cases. in the present case, we suggest that the best option for treatment of papillary thyroid carcinoma metastasis to skull would be surgery followed by radiotherapy.
