Rev Pediatr Aten Primaria [online]. 2012, vol.14, n.56, pp.312-316. ISSN 1139-7632.  https://dx.doi.org/10.4321/S1139-76322012000500005.

Primary hypothyroidism caused by chronic autoiummune thyroiditis is rare before the age of three years. We report the case of a two-year-old girl who presented symptoms of hypothyroidism at eighteen months of age: poor growth and delayed language development. Treatment wih thyroxine resulted in a markedly normalization of growth, language and laboratory data. We emphasize the importance of getting to a diagnosis and treatment as early as possible, including study of thyroid function in young infants with delayed growth. Early treatment is necessary to prevent irreversible neurological and growth deficits.
