Two Cases of Bone Metastasis from Follicular Thyroid Carcinoma Several Years after Initial Thyroidectomy

A 78-year-old woman presented with epigastric discomfort with nausea, and an abdominal CT revealed a rib mass and gall bladder polyp. She had had a subtotal thyroidectomy of a 4.2&#215;3 cm-sized follicular thyroid carcinoma 19 years ago. The rib mass was excised and its histological examination showed a metastatic carcinoma from a follicular thyroid carcinoma. One month later we carried out a completion thyroidectomy, and we will perform radioactive ablation with <SUP>131</SUP>I. A 64-year-old woman presented to our clinic for leg motor weakness and we found a T7 pathologic fracture by X-ray and MRI. She had had a left thyroid lobectomy for a minimal invasive follicular thyroid carcinoma measuring 4 cm at the greatest diameter. Anterior-decompression and fusion were carried out, and histological examination showed a metastatic lesion from the thyroid. Then we performed a completion thyroidectomy and <SUP>131</SUP>I radioactive ablation one month later. Radioactive ablation should be performed for large-sized follicular carcinomas to prevent recurrences. (Korean J Endocrine Surg 2012;12: 14-119)
