Abstract
A 19-year-old female underwent two radiofrequency ablation procedures for a thyroid tumor that was proven to be nodular hyperplasia versus a follicular neoplasm by fine-needle aspiration. Two years after the last follow-up, the thyroid mass had grown and a newly developed mass was detected in the platysma muscle. After surgery, the thyroid mass was revealed to be a solid papillary thyroid carcinoma, and the subplatysmal mass was tumor seeding.

Comments:
The original biopsy was not the ideal one for RFA therapy when there was a small but significant possibility of the nodule being cancer. Ultrasound imaging finding of a spongiform nodule 6 cm in size is the best nodule for RFA as they are uniformly benign.A second case of seeding occurred when a “benign” nodule seeded along the tract of a follicular carcinoma at surgery.

If you think you have a large spongiform symptomatic or cosmetic nodule call Matthew at 310-393-8860 and see if you are a candidate for RFA
