Her initial work-up revealed lung metastasis. She underwent a right thyroidectomy and then left thyroidectomy and laryngectomy, and subsequently received I-131 on 8 occasions. She had a drop in thyroglobulin levels to the early treatments, but most recently, thyroglobulin has steadily increased.

47-year-old female who had the onset of persistent vertigo. The first evaluations revealed right beating nystagmus on gaze straight and to the right, unsteady gait with limb ataxia, and positive head thrust to the left.
