A 45-year-old white woman with a previous history of myocardial infarction underwent resting gated blood pool scintigraphy to assess left ventricular function. She also had a previous history of hyperthyroidism treated in the past with antithyroid medications. Unexpected intense radiotracer activity was seen in the thyroid gland with a large cold nodule noted in the left lobe. No tracer was demonstrated in the stomach. Follow-up thyroid scanning confirmed the cold nodule in the left lobe and demonstrated an additional cold nodule in the right lobe. Radioactive iodine uptakes were elevated. Subsequent surgical removal of the gland showed a Hurthle cell adenoma in the left nodule and a focus of papillary carcinoma in the right nodule.
