A middle-aged male with relatively well-controlled HTN and DM was evaluated for unexplained microalbuminuria and renal calculi. On scrutiny of his previous reports, we discovered an adrenal incidentaloma and hypokalemia that had escaped attention before. The patient was investigated accordingly and finally found to have an aldosterone-producing adenoma (APA). He underwent unilateral adrenalectomy for APA that led to the resolution of hypokalemic HTN. This case highlights the significance of suspecting primary hyperaldosteronism in a patient with HTN with unexplained target organ damage, e.g., proteinuria.
