Advanced diagnostic approaches and current medical management of insulinomas and adrenocortical disease in ferrets (Mustela putorius furo)

Abstract

Endocrine neoplasia is the most common tumor type in domestic ferrets, especially in middle-aged to older ferrets. Islet cell tumors and adrenocortical tumors constitute the major types of endocrine neoplasms. Insulinoma is a tumor that produces and releases excessive amounts of insulin. Evaluation of fasted blood glucose levels provides a quick diagnostic assessment for the detection of insulinomas. Use of glucocorticoids, diazoxide, and diet modification are some of the medical treatment options for insulinomas. Adrenocortical neoplasia in ferrets usually overproduces one or more sex hormones. Sex hormones which can result in progressive alopecia, vulvar swelling in females, and prostagomegaly in males. Abdominal ultrasonography and sex hormone assays can be used to diagnose adrenocortical neoplasms. Drugs such as leuprolide acetate, deslorelin acetate, and the hormone melatonin can be used to treat adrenocortical neoplasms in ferrets when surgery is not an option.
