Clinical hyperthyroidism complicate 0.2 to 0.7% of pregnancies, mostly caused by Graves’ disease. A 26-years-old, pregnant woman, was referred to a tertiary center due to Graves’ disease. At 32-weeks, it was identified an enlargement of fetal thyroid gland. Cordocentesis confirmed fetal hypothyroidism. Maternal antithyroid drugs were suspended and intramniotic levothyroxine was administered, improving the thyroid function. The pregnancy ended at 37 weeks, with spontaneous vaginal delivery. Umbilical cord blood sample showed normal thyroid function. Fetal hypothyroidism should be thoroughly evaluated, diagnosed and treated, as it is a treatable cause of delayed psychomotor development.

Keywords : Fetal goiter; Fetal hypothyroidism; Cordocentesis.
