case_images: Post-thyroidectomy whole-body Iodine-131 scan showing radioiodine-avid foci in the neck and upper part of the left lung. Mild, irregular tracer uptake is also seen in both lung bases

case_images: A large radioiodine-avid focus was seen in the neck, in the midline, with an additional focus in the upper part of the left lung [Figure 1].
case_images: a) Hybrid SPECT-CT fusion shows I-131 uptake in the residual thyroid tissue on the left side of the neck; b-d) Multiple radio-opaque nodules are seen in both lungs, with radioiodine concentration in a few of these nodules

case_images: The focus in the neck was localized to the residual thyroid tissue, 1 cm below the lower border of the thyroid cartilage, on the left side [Figure 2a]. Radioiodine concentration was seen in a few of these nodules on the fused SPECT-CT images; most of the nodules did not show any radioiodine avidity at the dose used [Figure 2b-d].
case_images: Post therapy whole body scan shows extensive I-131 avid metastases in both lungs

case_images: The post-therapy I-131 WBS acquired there showed extensive I-131 avid metastases in both lungs [Figure 3].
