A 61-yr-old woman presented with complaints of weakness and pain in her legs. A magnetic resonance imaging showed a 3 x 5.6 x 7.8 cm mass lesion destructing the T1 and T2 vertebral bodies and compressing the spinal cord. The mass was excised surgically. It was follicular carcinoma metastasis of the cervicodorsal region. Then, she underwent a total thyroidectomy. Pathological examination showed two different types of carcinomas in two different focuses; follicular carcinoma in the left lobe and follicular variant papillary carcinoma in the isthmic lobe. After the operation she was given 100 mCi I-131. This is the first report of a patient who had both metastatic follicular carcinoma and follicular variant papillary carcinoma together.
