The onset of Graves' disease during pregnancy exposes the newborn to the risk of neonatal hyperthyroidism due to the transplacental passage of anti-thyroid-stimulating hormone (TSH) receptor antibodies. We report the case of a child whose mother was diagnosed with Graves' disease during pregnancy. Clinical hyperthyroidism appeared only a few days after birth and was confirmed by hormonal tests. Thanks to treatment with synthetic antithyroid drugs, the child's clinical and biological course was favorable. It is essential to systematically screen for neonatal hyperthyroidism in newborns of mothers with Graves' disease, as the absence of immediate clinical signs after birth does not rule out the diagnosis. The pediatrician must be aware of this thyroid condition even in the absence of an identified maternal history, in order to enable rapid therapeutic management.
