(1-4,7) Primary aldosteronism caused by adrenal cortical hyperplasia
usually presents in older individuals, has a predominance among males, is more often normokalemic, and has less severe hypertension.

Myelolipoma commonly presents as an isolated adrenal lesion, although myelolipomatous foci have been reported in association with various other adrenal pathologic conditions, including enzyme deficiencies, adrenal cortical hyperplasia
, and neoplasms of the adrenal cortex.
