A 7-year-old, neutered male cat was presented with a 6-month history of progressive polyuria, polydipsia, polyphagia, aggression, and weight gain. Previous blood work, urinalysis, and radiographs did not delineate a cause for the clinical signs. An ultrasound revealed bilateral adrenal gland enlargement. A low-dose dexamethasone suppression test was consistent with hyperadrenocorticism. Based on these findings, bilateral adrenalectomy was attempted and successfully performed. Histopathology was consistent with a cortical adenoma in the right adrenal gland and a pheochromocytoma in the left adrenal gland. This association has never been reported in the cat.

A 13 yr old castrated male vizsla was referred to the authors' institute because of polyuria, polydipsia, polyphagia, and weight loss. Pituitary-dependent hypercortisolism (PDH) was diagnosed by hormone testing and adrenal and pituitary imaging. Computed tomography (CT) revealed a pituitary mass measuring 21 mm in width. Medical therapy was initiated with trilostane. Despite adequate control of the hypercortisolemia, the polyuria and polydipsia persisted and the dog developed neurologic signs due to the pituitary mass effect. Pituitary transsphenoidal debulking surgery was performed and immunocytochemistry confirmed a corticotroph adenoma. The dog survived for 13 mo after surgery. Postmortem examination revealed an empty fossa without pituitary remnants and the presence of a malignant pheochromocytoma in the right adrenal gland. This case report demonstrates, for the first time, that a large pituitary adenoma in the dog may be treated successfully by pituitary surgery.
