Abstract
A 16-year-old, male, Hanoverian horse had a three-month history of weight loss, hirsutism and polyuria/polydypsia. Examinations revealed neutrophilia, lymphopenia, hyper glycaemia and abnormalities in hepatic function. A tentative diagnosis of hyperadrenocorticism was made. The results of thyroid-releasing hormone and combined dexamethasone suppression and ACTH stimulation tests suggested the presence of a pituitary adenoma. The horse was treated with pergolide and beneficial clinical and biochemical responses were observed within one to six months.
