Case report: functioning pituitary macroadenoma in Boston Terrier

An eight-year-old male Boston Terrier breeding canine was brought to Clinica San Miguel Medicina Veterinaria, with a six-month history of temperament changes, marked lethargy and alteration of liver function with previous treatment in another veterinary center. The patient manifested increased hepatic transaminases ALT and GGT, ultrasound alteration in adrenal glands with increased size, a diagnosis of hyperadrenocortisism was made by means of suppression test with dexamethasone at low doses with increased cortisol; its cause was confirmed by brain contrasted MRI in which pituitary mass was evidenced; leading to the diagnosis of pituitary adenoma producing ACTH, consistent with what is reported in literature and therapeutic alternatives with its clinical signs.
