FIGURE 4. Thyroid inflammation. (A) Patient with known squamous cell carcinoma of upper lobe of right lung (thick arrow) who was being evaluated for initial staging. Note intense thyroid uptake due to Hashimoto’s thyroiditis. Also note normal stomach uptake (thin arrow). (B) A 57-y-old woman with history of breast carcinoma and left thyroidectomy who was being evaluated because of rising levels of tumor markers. Neck uptake was due to Hashimoto’s thyroiditis, which could easily have been mistaken for nodal uptake. C = coronal.
