Figure 2: (a and d) Anterior neck images of I-123 whole body scan (WBS) showed abnormal radiotracer uptake (arrow) at the anterior midline of the neck, suggesting the presence of functioning thyroid tissue in thyroglossal duct remnant (TGDR) as well as another remnant uptake in the thyroid bed.(b and e) Anterior neck images of I-131 WBS after ablation therapy showed tracer uptake in the corresponding areas in both patients, confirming the presence of TGDR. 6 months later (c) anterior neck images of I-131 diagnostic whole body scan showed residual uptake at the area of TGDR in the first patient, and (f) no evidence of functioning thyroid tissue in the neck of the second patient indicating successful ablation
