Abstract
A 51-year-old woman was admitted because of a thyroid tumor and development of paralysis of the lower half of the body. Physical examination and a 201T1-chloride whole-body scan disclosed a metastatic lesion in the 11th thoracic vertebra. Four days after admission, the patient underwent a laminectomy which relieved the symptoms of lower-half paralysis. One month later, a total thyroidectomy was carried out and after one further month, radioiodine treatment was carried out. The spinal lesion decreased in size after two sessions of 131I treatment and the serum thyroglobulin level markedly decreased from 5, 500ng/ml to 950ng/ml.
