Overview
Ultrasound
The best initial test to diagnose hypoaldosteronism include measuring plasma renin activity and aldosterone levels. However, ultrasound may be helpful in the diagnosis of hypoaldosteronism from disorders of renal or adrenal glands.
- Hypoaldosteronism from chronic kidney disease may show the following features on ultrasound:
- Reduced renal length
- Reduced renal cortical thickness
- Increased renal cortical echogenicity
- Poor visibility of the renal pyramids and the renal sinus
- Renal marginal irregularities
- Renal papillary calcifications
- Renal cysts
- Hypoaldosteronism due to adrenal disorders may present with following findings on ultrasound:
- Irregularly shrunken adrenal glands
- Adrenal nodules
- Signs of calcium deposits
