Differentiated thyroid cancers have indolent clinical course and good prognosis with an approximate 85–90% 10-year survival rate. Distant metastases from follicular thyroid cancer are uncommon but are one of the main causes of cancer-specific mortatily. Mainly involve the lung, bone, and brain. Bone metastasis most commonly occurs in the vertebrae, costas and hip bones. Metastasis of a follicular thyroid carcinoma to the skull is very rare and only a small number of reports are found in the literature. We present a case of solitary lytic skull metastasis of a follicular thyroid cancer in a 79-year-old woman. The patient presented with a painless mass on the right side of the head. Physical examination showed a large, palpable, immobile and hard tumor. CT scan showed thyroid enlargement along with neck lympadenopathy and a lesion with an osteolytic component in the right parietal area.
