Abstract
Thyroid ecography was performed in 29 patients with CH and, thyroid scanning with tecnecium was performed in 26. Twenty two cases of thyroid dysgenesis were identified by scanning. 14 had athyreosis, 2 had hypoplasia and 6 had an ectopic gland. In all 22 cases, a concommitant ecographic study showed an absent gland in the cervical region. In the other 3 patients, which were not scanned, ecographic studies identified a detectable gland, which was compatible with the diagnosis of thyroid dysgenesis. In 3 patients, the ecography identified gland at the usual site, which concentrated isotope in two cases, and did not concentrated in the third, compatible with abnormal synthesis or secretion. In one, there was a large goiter, clinically palpable at birth. Another case was of recurrent CH in the same family, characterized by autosomic inheritance suggesting dishormonogenesis. The third case appeared to represent a possible TSH receptor defect or a trapping abnormality. In one case, the gland was identified by both diagnostic procedures. It was our only case of transitory CH. In conclusion, ecography is a very sensitive method for the diagnosis of thyroid dysgenesis, although it cannot discriminate the form. On the other hand, identifing gland in a suspicious case of CH suggests dyshormonogenesis or transitory CH, which has important clinical implications.
