Background: Thyroid carcinoma initially presents with clinical symptoms due to metastatic lesions in less than 5% of cases. Spinal cord compression from an epidural metastatic lesion as a first symptom is extremely rare. One would expect such a presentation to occur much later in the course of the disease. Case presentation: We report an unusual case of a 57-year-old-woman with the complaint of back pain for one year. A process was detected at the corpus of L5-S1 to S3 vertebra, by the sacrococcygeal MRI. Conclusion: Spinal metastasis as initial finding is very rare in the patients with FTC. However, prognosis is quite well with total tumor resection and adjuvant treatment. This cancer type must be kept in mind for differential diagnosis and must be screened in the patients with spinal tumors.
