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.
