PASSAGE
A 70-year-old man with a history of atrial fibrillation maintained on amiodarone for the last three years presents with new-onset anxiety and a 10-lb weight loss. His thyroid gland is non-tender. Labs reveal a TSH of <0.01 µIU/mL and a free T4 of 4.2 ng/dL. A color Doppler ultrasound of the thyroid is performed.
Which finding on the ultrasound would most strongly suggest amiodarone-induced thyrotoxicosis (AIT) Type 1?
