The thyroid ultrasound scan showed an enlarged right lobe of the thyroid gland with multiple hypoechoic nodules and increased vascularity shown on color flow. Technetium-99m thyroid scan was then carried out which revealed an increase in the size of the thyroid gland with reduced and patchy tracer uptake and these findings reflected subacute thyroiditis (Fig. 1).
