Abstract
Thyroid is particularly prone to morphogenetic variability. Developmental
failure of the thyroid gland is in 85% of cases the
underlying cause of congenital hypothyroidism, diagnosed at
birth with a frequency of 1:3000–1:4000 newborns. However, the
incidence of less severe developmental variants of the thyroid
is much higher. Determination of the aetiology of congenital
hypothyroidism is crucial for predicting its severity and outcome
as well as impacts dose of L-thyroxine during substitution. Thyroid
imaging is necessary to establish diagnosis, and it involves
mainly thyroid ultrasound examination and scintiscan. Awareness
of both the advantages and limitations of sonographic and
scintigraphic imaging are central to the successful interpretation
of their results and reasonable recommendation of these procedures
for patients with thyroid developmental anomalies of
different age and clinical picture. Hence, the aim of this review
is to provide the most important and up-to-date information on the place of radionuclide scanning and ultrasonography in
visualization of different thyroid developmental abnormalities.
