[Spinal cord compression as a primary manifestation of occult thyroid carcinoma].

Metastatic disease is the first clinical manifestation of differentiated thyroid carcinoma (DTC) in less than 5% of cases. Bone metastases as the first sign of DTC are associated with a poor prognosis, both for being resistant to treatment and for complications due to them. Spinal cord compression is a rare development in DTC, which may present late in the course of the disease. An initial presentation of DTC with a spinal cord compression is an extremely rare condition.
