Abstract

A 45-year-old female patient visited our thyroid center with thyrotoxic symptoms and bulging of left neck. Ultrasonogram showed a 3.1 cm sized solid thyroid nodule. The serum TSH level decreased (0.005 u/ml, normal range; 0.4∼4.0 u/ml), however the serum T3 and FT4 levels were within normal limit. 99mTc pertechnate scintigraphy showed a hot nodule in her left thyroid gland and suppression of the extra-nodular uptake. As she refused surgery and 131I radioiodine therapy, radiofrequency ablation was recommended. After two treatment sessions, the serum TSH level was normalized and hyperthyroid symptoms had resolved. At the 16-month follow-up, the hot nodule was invisible and the suppressed extra-nodular uptake had returned to normal. Radiofrequency ablation is a feasible minimally invasive modality for the treatment of an autonomously functioning thyroid nodule.
