Overview

There are no specific CT findings associated with Addisons's disease. However, the ct may show findings of bilateral adrenal remnants and calcifications suggesting autoimmune adrenalitis or tuberculosis adrenalitis.

CT Scan

Abdominal CT findings in Addison's disease may include:[1]

  • Small adrenal remnants bilaterally suggestive of autoimmune adrenalitis, idiopathic atrophy, or long-term tuberculosis infection.
  • Dense calcification in one or both adrenal beds without evidence of normal glandular remnants - in TB.
  • Enlarged nonhomogeneous glands of normal contour - in Histoplasmosis.
  • Atrophic adrenal glands - in idiopathic autoimmune Addison's disease.
