| Abstract: | Congenital hypothyroidism and dysmaturity syndrome (CHD) in neonatal foals was first described in western Canada in 1981 and remains an important problem for the western Canadian horse industry. This syndrome is characterised by hyperplasia of the thyroid gland, increased gestational length and multiple congenital musculoskeletal abnormalities. This case series describes the first confirmed cases of CHD in Europe and challenges contemporary opinion which suggests that this syndrome is distinct from congenital hypothyroidism associated with visible goitre. |
