The occurrence of tumors in wild felids has been on the rise in recent years due to the increased longevity of animals kept under human care. However, the occurrence of adrenal tumors in these felids is low. In the lion (Panthera leo) there has only been one report of an adrenal adenoma. Most adrenal tumors lead to an imbalance in the adrenal hormones, whether glucocorticoids (cortisol), mineralocorticoids (aldosterone) or sex hormones. When there is an increase in cortisol, the symptoms originate from the immunosuppressive, anti-inflammatory and catabolic effects of glucocorticoids. Increased aldosterone production results in hypertension, hypokalemia, electrolyte disorders and metabolic alkalosis. This paper reports the case of a 20-year-old lioness, kept in a zoo, who presented a carcinoma of the right adrenal gland and symptoms compatible with hyperaldosteronism.
