Thyroiditis in a 56-year-old woman with metastatic melanoma treated with ipilimumab / nivolumab. CT (A) and fused FDG PET/CT images (B) acquired 2.5 months after treatment initiation revealed marked FDG uptake in the thyroid gland consistent with thyroiditis; the patient had thyrotoxicosis at the time of the scan, which was followed by persistent hypothyroidism requiring levothyroxine replacement. Follow-up CT (C) and fused FDG PET/CT images (D) obtained 1 year later demonstrated resolution of the abnormal uptake in the thyroid gland.
