[Correct procedure in the presence of a fetal goiter associated with hypothyroidism. Observations from three cases]

Fetal goiter is a rare occurrence of which neonatal consequences are not always predictable. Concerning three cases of goiters associated with hypothyroidism discovered in utero, the authors describe the way to take care of in this bad codified situation. They insist upon the major role of ultrasound for goiter diagnosis and its impacts and for control of treatment efficiency. They also discuss intra amniotic L-Thyroxine injection and insist upon the necessity to obtain quick and definite thyroid evaluation after birth before decision to abstain from neonatal therapy.
