To the Editor: Basaria and Salvatori (March 25 issue) present superb photographs of a patient with Pemberton's sign in Images in Clinical Medicine.¹ However, the accompanying computed tomographic (CT) scan of the thyroid gland appears to have been performed with the use of radiographic contrast material. The use of iodinated radiographic contrast agents may be contraindicated in patients with large goiters because of the risk of provoking iodine-induced hyperthyroidism and the subsequent difficulty in obtaining nuclear medicine images of the thyroid, if needed. We believe that non-contrast CT would have been a more appropriate means to study this patient.
