[Imaging of adrenal incidentalomas]

Area of Science:

• Radiology
• Endocrinology
• Oncology

Context:

• Adrenal incidentalomas are frequently discovered during imaging studies for other conditions.
• Distinguishing benign from malignant adrenal masses is critical for appropriate patient management.
• Current imaging modalities face challenges in definitively characterizing these lesions.

Purpose:

• To review current imaging techniques for evaluating adrenal incidentalomas.
• To discuss diagnostic approaches for differentiating benign from malignant adrenal masses.
• To outline management strategies for incidentally discovered adrenal tumors.

Summary:

• Unenhanced CT scans and chemical shift MRI are valuable tools for assessing adrenal incidentalomas.
• These imaging methods identify lipid content, a key feature distinguishing benign adenomas from nonadenomas.
• Accurate characterization aids in avoiding unnecessary interventions for benign lesions.

Impact:

• Improved diagnostic accuracy for adrenal incidentalomas.
• Facilitation of appropriate clinical decision-making and patient management.
• Reduction in unnecessary invasive procedures for benign adrenal masses.
