Purpose: Congenital hypothyroidism results from thyroid dysgenesis (85 – 90%), i.e. an error of thyroid development, or from dyshormonogenesis (10 – 15%), i.e. inborn errors of thyroid hormone synthesis or secretion. In thyroid dysgenesis, ultrasonography shows an absent, ectopic or hypoplastic thyroid gland. Dyshormonogenesis, in contrast, usually is associated with neonatal goiter. Echogenicity and echotexture of such enlarged thyroid glands have been reported to be normal with typical vascularization on Duplex imaging. We have evidence that this statement very probably is not correct; at least it does not app…
