A 63 year old male who was found to have papillary thyroid cancer on the FNA of a cold thyroid nodule, presented post thyroidectomy for remnant ablation. Pre-treatment I-131 scan showed focal uptake in the thyroid bed consistent with thyroid remnant and a focus of uptake superior to the thyroid remnant in the midline neck.
SPECT-CT localized this focus of uptake to the base of the tongue, in the region of foramen cecum, consistent with a thyroglossal duct remnant.
Remnant ablation was preformed with 100 mCi of I-131 and was well tolerated.
A one year follow up I-131 whole body scan showed the resolution of the thyroid remnant and thyroglossal duct remnant.

This blog provides very useful information for anyone researching treatment options for thyroid nodules. I liked how you explained the role of a qualified Thyroid RFA Doctor in ensuring safe and effective treatment outcomes. Radiofrequency ablation is becoming increasingly popular because it offers a minimally invasive alternative to surgery, and your article highlights these advantages perfectly. The details about recovery time, procedure benefits, and patient care were especially helpful. It’s important for patients to understand that choosing the right doctor with proper expertise and experience can greatly improve treatment confidence and results. Thank you for creating such an educational and easy-to-understand post on this important healthcare topic.
