Adrenal incidentaloma

Area of Science:

• Endocrinology
• Oncology
• Radiology

Background:

• Adrenal incidentalomas are adrenal tumors discovered incidentally during imaging for unrelated conditions.
• They may be asymptomatic, necessitating careful evaluation.
• Classification includes non-hypersecreting adenomas, hypersecreting tumors, primary adrenal carcinoma, and metastases.

Purpose of the Study:

• To outline the diagnostic and management strategies for adrenal incidentalomas.
• To emphasize the importance of assessing hormonal activity and malignancy.
• To guide clinical decision-making for these incidentally discovered adrenal lesions.

Main Methods:

• Comprehensive hormonal evaluation to detect subclinical hormone hypersecretion (e.g., Cushing's, pheochromocytoma, aldosteronoma).
• Radiologic assessment, including imaging characteristics and potentially fine needle biopsy, to determine malignancy.
• Classification based on hormonal status and tumor characteristics.

Main Results:

• The majority of adrenal incidentalomas are non-hypersecreting adenomas, but hypersecreting tumors must be ruled out.
• Hormonal evaluation is crucial for identifying conditions like subclinical Cushing's syndrome, pheochromocytoma, and aldosteronoma.
• Malignancy assessment is vital, guiding treatment decisions.

Conclusions:

• Adrenal incidentaloma management requires a dual approach: assessing hormonal activity and determining malignancy.
• Surgical intervention is indicated for hormonally active tumors or inactive tumors exceeding 4 cm.
• Non-operative management involves regular monitoring of hormone levels and tumor size for selected cases.
