Figure 25.10 A 12-year-old Maine Coon presented for history of weight loss, systemic hypertension, and hypokalemia. The baseline
aldosterone was significantly elevated. A mass is identified involving the right adrenal gland on abdominal radiographs (a) and
ultrasound (b). The left adrenal gland is normal in size (c). A postsurgical complication was the development of a clot within the
caudal vena cava which resulted in progression of renal disease.
