Plain-English summary

A 16-year-old male Hanoverian horse had been losing weight, growing an unusual amount of hair, and drinking and urinating a lot for the past three months. Tests showed some issues with his white blood cells, blood sugar levels, and liver function, leading to a suspected diagnosis of Cushing's syndrome (a condition caused by too much cortisol). Further tests indicated he likely had a pituitary tumor. After starting treatment with pergolide, the horse showed positive changes in his health and blood tests within one to six months.

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.
