Adrenal Incidentaloma

List of authors.
  • Electron Kebebew, M.D.

An adrenal mass discovered in testing for another condition (an ¡°incidentaloma¡±) warrants biochemical tests to detect pheochromocytoma, excess cortisol, and, in a patient with hypertension, primary hyperaldosteronism. Imaging may distinguish benign from malignant lesions. Small nonfunctioning adrenal tumors with low CT attenuation generally do not warrant intervention or long-term follow-up.
