Abstract:

Background: Thyroid nodules constitute a frequently seen clinical problem and the incidence of thyroid nodules has increased with the recently increased use of thyroid ultrasonography. Radiofrequency ablation (RFA) is an effective and safe method for treating benign thyroid nodules and recurrent thyroid cancers. Case Presentation: A 48 years old woman came to the surgical oncology clinic with the presence of a getting bigger, moves when the patient swallows, and painless mass on her neck since 20 years ago. The physical examination measured 5x5 cm mass, mobile on swallowing, no pain on palpation, and the laboratory examination shows a euthyroid state.  The ultrasound result has revealed an enlargement of the right and left thyroid with increased echo intensity of parenchyma and increased vascularisation. This mass was concluded as struma nodus bilateral. The FNAB was follicular neoplasm, Bethesda system class 4. The patient underwent a single session RFA. RFA was performed employing transisthmic access using a 7 cm 18 gauge electrode-needle with a 1 cm active needle tip. The patient well tolerated the procedure and no adverse events were noted.   Conclusion: Radiofrequency ablation for thyroid lesions is a safe and effective method for treating benign thyroid nodules and even recurrent thyroid cancers. Therefore, various factors, including serum TSH, clinical risk factor assessment, size of the nodule, ultrasound characteristics, patient preferences, and results of the FNA biopsy, should be considered to manage thyroid nodule.
