Primary aldosteronism with bilateral adrenal adenomas

Area of Science:

• Endocrinology
• Pathology
• Surgical Oncology

Background:

• Primary aldosteronism is a common cause of secondary hypertension.
• Bilateral adrenal adenomas are a rare cause of primary aldosteronism.
• Accurate tumor localization is crucial for effective treatment.

Observation:

• A patient presented with primary aldosteronism and bilateral single adenomas.
• Computerized axial tomography identified two adrenal tumors.
• Spironolactone therapy induced spironolactone bodies in only one adenoma.

Findings:

• Spironolactone bodies are cytoplasmic inclusions potentially indicating adenoma activity.
• The unilateral presence of spironolactone bodies suggests a single active adenoma.
• This finding supports a unilateral source of hyperaldosteronism.

Implications:

• Spironolactone bodies may serve as a reliable indicator of functional localization in primary aldosteronism.
• The presence of these bodies could enhance diagnostic accuracy beyond imaging.
• This observation may refine pre-operative assessment and treatment strategies for primary aldosteronism.
