This has been centred on the vertebral body of D7, with spinal canal invasion (Fig. 1), causing spinal cord compression and myelopathy, which raised suspicions of bone metastasis from an occult tumour.
Anatomopathological analysis.. A Cytology (200x), a group of neoplastic follicular cells with hematic background; B) Bone metastasis (HE 100x); C) Bone metastasis (thyroglobulin 200x); D) Follicular thyroid carcinoma (HE 40x); E) Follicular thyroid carcinoma (HE 40x), tumour capsule invasion; F) Follicular thyroid carcinoma (HE 200x).

This morphologic and immunohistochemical pattern was compatible with bone metastasis from a follicular thyroid carcinoma (Fig. 2).
