    Summary

    Serial computed tomography (CT) scans can help identify benign adrenal masses. Criteria include size, smooth contour, defined margins, and no change in size over time, potentially avoiding surgery.

    Area of Science:

    • Radiology
    • Endocrinology
    • Oncology

    Background:

    • Adrenal masses are common findings.
    • Differentiating benign from malignant adrenal tumors is crucial for patient management.
    • Non-functioning adrenal masses require careful evaluation to avoid unnecessary interventions.

    Purpose of the Study:

    • To establish criteria for identifying benign adrenal masses using computed tomography (CT).
    • To evaluate the role of serial CT scanning in managing patients with adrenal masses.
    • To determine if imaging characteristics can obviate the need for surgical intervention.

    Main Methods:

    • Retrospective study of 18 patients with unilateral non-metastatic, non-functioning adrenal masses.
    • Utilized computed tomography (CT) for initial assessment and serial follow-up.

  • Pathological examination of 6 confirmed cases of adrenal adenoma.

    • Main Results:

    • Six cases confirmed as benign adrenal adenoma via pathology.
    • Remaining masses showed no change in size over 6 months to 3 years of follow-up.
    • Proposed criteria for benign adrenal mass: diameter < 5 cm, smooth contour, well-defined margin, and stability on serial CT.

    Conclusions:

    • Serial CT scanning is a valuable tool for managing adrenal masses.
    • Imaging criteria can reliably suggest a benign adrenal mass.
    • Conservative management with serial CT may be a safe alternative to surgery for select patients.
