Graves’ disease is by far the most common cause of hyperthyroidism in children [1]. In this specific population, the hyperthyroidism is willingly biochemically overt and clinically severe [2]. Childhood hyperthyroidism may also cause accelerated growth and bone maturation, and eventually deterioration in academic performance, hence the need for a good screening and a better management. children with GD require prompt treatment, for the most of cases it’s initially medical. But once this fails or is not possible, a definitive treatment should be considered [3]. For the antithyroid drugs use, we currently consider no difference in biochemical control between DT and BR [2,4], unlike previous approaches which argue in favor of the use of bloc-replace method in children [5-6]. However, for a curative treatment, total thyroidectomy is the preferred option for GD patients younger than 10 years [3]. We report the case of a girl who was 2 and a half years old in the moment of diagnose, and whom we followed for Graves' disease for 1 and a half years.
