title: A unique case of thyroid dysgenesis in a neonate.
abstract: Neonates with congenital hypothyroidism often demonstrate ectopic thyroid tissue. However, 2 sites of abnormally located thyroid tissue are exceptionally rare with only one other published case on a neonate. The authors present a unique case of a neonate who was found to have congenital hypothyroidism on laboratory screening; Tc-99m pertechnetate scintigraphy demonstrated 2 sites of abnormal uptake: one at the base of the tongue and the other in the midline at the expected location of the thyroid bed.
