General NM case of the month (07/10): Thyroglossal Duct Remnant
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.
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.
