Ultrasonography in congenital hypothyreosis.
To our knowledge, ultrasonography has not so far been used as an additional source of information in the early screening for congenital hypothyreosis. This study demonstrated, firstly, that the normal neonatal thyroid gland could always be recognized by ultrasonography and, secondly, that in congenital hypothyreosis absence of thyroid tissue from the normal site could be detected by ultrasonography, whereas ectopic tissue in the tongue could not readily be identified. The findings may be useful in the diagnosis of congenital hypothyreosis.
