How is hyperadrenocorticism diagnosed?
Firstly, a full medical history and thorough physical examination will be performed to determine what clinical signs are present. Other diseases, such as diabetes mellitus or hypothyroidism, may have similar signs. The veterinarian will differentiate hyperadrenocorticism from these other diseases based on physical examination and diagnostic testing. A variety of blood tests and urinalysis may be done to evaluate the animal. Some highly specific tests, such as dexamethasone suppression test or adrenocorticotrophin (ACTH) stimulation test, may be performed to provide a definitive diagnosis and to determine whether an adrenal gland or pituitary tumour is present. Radiographs (X-rays) of the abdomen and chest may help detect primary tumours and metastasis (the spread of the cancer to other parts of the body). Other imaging techniques such as ultrasound are often useful. Pets with hyperadrenocorticism may have additional medical problems, such as diabetes mellitus or urinary tract infection
