Primary hyperaldosteronism secondary to right adrenal hyperplasia with non‐functioning left adrenal adenoma elucidated by adrenal vein sampling: A case report with in‐depth physiological review on utility of aldosterone renin ratio

Abstract

Key Clinical Message In cases of primary hyperaldosteronism, the aldosterone renin ratio (ARR) is crucial for determining the need for adrenal vein sampling (AVS). Our case highlights the importance of utilizing ARR with AVS, contextual interpretation of plasma renin and aldosterone levels, and stresses that sole reliance on imaging without AVS may result in unnecessary or contralateral adrenalectomy.
