case_images: Diagnostic scan with 123-Iodine. A shows the SPECT-CT scan demonstrating increased iodine uptake in the medial portion of the patient's left orbit. B shows the whole-body iodine scan. This scan demonstrates the physiological uptake of the salivary gland and remnant thyroid as well as the irregularity of iodine uptake in the left orbit.

case_images: TSH (Thyrogen)-stimulated diagnostic scan with I-123, during which the stimulated thyroglobulin was 4.7 ng/mL. The pretherapy diagnostic scan (Fig. 1) was notable for a small amount of residual functioning thyroid tissue in the thyroidectomy bed and physiological activity in the salivary glands. Of note, the planar and SPECT-CT images (Fig. 1A and 1B) showed evidence of a large focus of marked radioiodine retention along the inferomedial aspect of the left orbit.
