Overview
Key CT Findings for Adrenal Insufficiency
- CT scan findings in primary adrenal insufficiency include:
- Small adrenal remnants bilaterally
- Dense calcification in one or both adrenal beds without evidence of normal glandular remnants - in TB[1]
- Enlarged nonhomogeneous glands of normal contour - in Histoplasmosis
- Atrophic adrenal glands - in idiopathic autoimmune Addison's disease.
- In secondary and tertiary adrenal insufficiency the following findings may be seen on CT head:
- Calcified pituitary and/or hypothalamus.
- Pituitary adenomas - micro / macro
- Absent pituitary and/or hypothalamus - surgical removal
