Summary
Adrenal incidentalomas (AI) require careful evaluation for hormonal activity and malignancy. Early diagnosis and management, including adrenalectomy for specific cases, are crucial for patient outcomes.
Area of Science:
- Endocrinology
- Oncology
- Radiology
Background:
- Increased detection of adrenal incidentalomas (AI) due to advanced imaging.
- AI management poses a clinical challenge, requiring assessment of hormonal activity and malignancy risk.
Purpose of the Study:
- To outline diagnostic and management strategies for adrenal incidentalomas.
- To identify key steps in evaluating adrenal masses for hormonal function and malignant potential.
Main Methods:
- Recommended screening tests include dexamethasone suppression test, metanephrine assays, and aldosterone/renin ratio.
- Imaging features and fine-needle aspiration biopsy aid in distinguishing benign from malignant masses.
- Surgical intervention (adrenalectomy) is indicated for functional or suspected malignant adrenal masses.
Main Results:
- Most AI are non-hypersecretory cortical adenomas, but subtle hormone excess can be identified.
- Masses >4 cm and specific imaging features increase malignancy risk.
- Adrenalectomy is recommended for functional masses or suspected malignancy, particularly with comorbidities.
Conclusions:
- A systematic approach to AI diagnosis and management is essential.
- Early identification of hormonal activity and malignancy risk guides treatment decisions.
- Close follow-up is necessary, especially within the first year post-diagnosis.
