Plain-English summary
A 12-year-old male shorthaired cat was brought in for weakness due to low potassium levels, despite receiving potassium supplements. Tests showed that he had a large adrenal tumor causing a condition called hyperaldosteronism, which led to his symptoms. The tumor was surgically removed, but complications arose from the surgery, resulting in kidney failure. Unfortunately, the cat had micrometastases (small spread of cancer) found in his lungs at the time of autopsy, indicating that the cancer had spread.

Abstract
In a 12-year-old male shorthaired cat with attacks of hypokalaemic muscular weakness in spite of oral potassium supplementation, highly elevated plasma aldosterone concentrations in combination with low plasma renin activity pointed to primary hyperaldosteronism. Ultrasonography and computed tomography revealed a large left-sided adrenal tumour growing into the phrenicoabdominal vein and the caudal vena cava. The tumour and its intravascular extension were surgically removed, but the subsequent stenosis of the caudal vena cava caused congestion and renal failure. At autopsy pulmonary micrometastases of the aldosteronoma were found.
