Most functioning lesions are benign adenomas whereas malignant lesions are usually non-functioning.
Larger adrenal masses may be identified as well on ultrasonography Hyperplastic conditions rather than actual tumors can cause both Cushing's or Conn's disease as well. Hyperplasic adrenal glands are either normal on CT or demonstrate bilateral uniform enlargement. Non-functioning adrenal adenomas are relatively common. Certain malignancies, such as bronchogenic carcinoma, have a tendancy to metastasize to the adrenal glands. Anderson and Wastie.
