摘要

Hypothyroidism results in decreased production of the thyroid hormones thyroxine (T_4) and triiodothyronine (T3) from the thyroid gland. At least 95% of cases of canine hypothyroidism are believed to be due to acquired primary hypothyroidism. Destruction of the thyroid gland can result from lymphocytic thyroiditis, idiopathic thyroid atrophy, or rarely neoplastic invasion. Secondary hypothyroidism (deficiency of TSH) is well described in humans but uncommonly recognized in the dog. Causes of acquired secondary hypothyroidism in the dog include pituitary neoplasia and pituitary malformations such as cystic Rathke's pouch. Tertiary hypothyroidism (deficiency of TRH) has not been documented in dogs.
