Summary

Incidental adrenal tumors discovered during imaging require careful evaluation. Tumors over 3.5 cm warrant surgery due to potential malignancy, while smaller ones need monitoring via computed tomography (CT) scans.

Area of Science:

  • Endocrinology
  • Radiology
  • Oncology

Background:

  • Non-functioning adrenal tumors are often found incidentally during imaging for other conditions.
  • It is crucial to differentiate these incidental adrenal masses from metastatic disease in cancer patients.

Purpose of the Study:

  • To present findings on the management of incidentally discovered non-functioning adrenal tumors.
  • To establish criteria for surgical intervention versus conservative management.

Main Methods:

  • Retrospective review of twelve cases of incidentally discovered non-functioning adrenal tumors.
  • Utilized computed tomography (CT) for tumor assessment and follow-up.
  • Surgical intervention was based on tumor size and characteristics.

Main Results:

  • Adrenal tumors found in patients with known malignancies were not always metastases.
  • Tumor size >3.5 cm was identified as a key indicator for potential malignancy and surgical consideration.
  • Smaller tumors (<3.5 cm) managed conservatively showed no significant changes in contour, margin, density, or hormone function during a one-year follow-up via CT.

Conclusions:

  • Size is a critical factor in managing non-functioning adrenal tumors.
  • Surgical intervention is recommended for adrenal tumors exceeding 3.5 cm.
  • Regular CT surveillance is effective for smaller adrenal tumors, with changes indicating potential malignancy and need for surgery.
