Résumé : Ultrasonography of the neck in a 28 week-old fetus suggested the presence of a goiter. Since sonographic evaluation of epiphyseal ossification centers showed no delayed bone maturation, the fetus was considered to have an euthyroid goiter, that allowed amniocentesis to be performed. The fetus was sonographically followed from 32 to 36 weeks: the development was normal. At birth, hormonal tests confirmed an euthyroid goiter. The authros consider that bone maturation should be monitored in utero especially when a thyroid dysfunction is suspected, in order to detect severe disease and to prompt treatment.
