Once the diagnosis of congenital hypothyroidism (CHT) is established by the screening tests, it is mandatory that the etiology, the severity and the prognosis of the disease should be confirmed as soon as possible. It is necessary to distinguish between patients with transient hypothyroidism, dyshormogenesis, ectopic thyroid or complete athyreosis. The Second International Conference on Neonatal Thyroid Screening (1) reported that 90% of primary congenital hypothyroidism is caused by thyroid dysgenesis, about two-thirds being thyroid ectopia and one third agenesis. These conditions are easily identified on the basis of the morphological abnormalities shown in thyroid scintigraphy. Thyroid scintigraphy is at present used extensively throughout all the screening centres in the world (2–7).
