Graves’ disease is an autoimmune disorder of the thyroid which is characterized by hyperthyroidism and frequently accompanying diffuse goiter. Thyroid scan reveals diffuse bilateral increased uptake of radioisotopes. Unilateral involvement of the thyroid gland on thyroid scan in patients with Graves’ disease is a rare entity. Here we present two cases of Graves’ disease who had unilateral involvement of the thyroid gland.
