An unusual cause of progressive quadriparesis.

Thyroid carcinoma is a rare cause of compressive myelopathy. Quadriparesis as the presenting manifestation of follicular carcinoma of thyroid without any preceding features of malignancy is quite uncommon. We describe a case of a 55-year-old woman who presented with progressive quadriparesis of 2 months duration, on evaluation was found to have a large tumor destroying C1, C2 vertebrae and occupying craniovertebral junction. Histopathological examination of excised tumor was follicular thyroid carcinoma. She was successfully managed with surgical excision, stabilization of spine followed by radiotherapy.
