RT Journal Article SR Electronic T1 Functioning Metastases from Thyroid Papillary Carcinoma in Bone JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 253 OP 254 DO 10.2967/jnmt.116.174573 VO 44 IS 4 A1 Biyi, Abdelhamid A1 Zaïmi, Soukaina A1 Doudouh, Abderrahim YR 2016 UL http://tech.snmjournals.org/content/44/4/253.abstract AB Functioning thyroid metastases are a rare cause of hyperthyroidism. Most are follicular carcinoma. Here, we report a case in which a 62-y-old man with a history of right subtotal thyroidectomy for a benign adenoma complained of symptoms of hyperthyroidism associated with left arm pain. Biopsy of a humeral lesion was consistent with papillary carcinoma metastatic from the thyroid. Postoperatively, the patient received a cumulative dose of 14.8 GBq of 131I with good control of the hyperthyroidism but without eradication of the bone metastasis.
