Issue Date: | 2013 | Journal: | Endocrinology, Diabetes and Metabolism Case Reports | Abstract: | A man underwent total thyroidectomy for goiter when he was 62 years old. The pathology report informed on a 5.5 cm oncocytic follicular adenoma and a 3.5 mm papillary microcarcinoma. Due to the papillary tumor, he was treated with ablative radioiodine therapy and suppressive doses of levothyroxine. After uneventful follow-up for 9 years, increased levels of serum thyroglobulin were detected. Further imaging studies including a whole body scan (WBS) after an empirical dose of 200 mCi 131I were negative. Two years later, a 99mTc SestaMIBI WBS and a 2-[18F]-fluoro-2-deoxy-D-glucose positron-emission tomography showed a well-delimited focal uptake in the right femur. A bone biopsy of the lesion demonstrated metastasis of follicular thyroid carcinoma. Retrospective histological reexamination of available material from the primary oncocytic thyroid tumor failed to reveal definitive traits of malignancy. | URI: | http://hdl.handle.net/10553/106567 | ISSN: | 2052-0573 | DOI: | 10.1530/EDM-13-0051 | Source: | Endocrinology, Diabetes and Metabolism Case Reports [ISSN 2052-0573], v. 2013(1) |
