Current diagnostic approach to adrenal abnormalities.

Cross-sectional imaging of the adrenal glands is described, and examples of pheochromocytoma, bilateral adrenal hyperplasia, aldosteronoma, and metastasis are presented. The clinical diagnosis and radiologic findings of these and other adrenal lesions are discussed. Noninvasive and invasive procedures, and their usefulness in diagnosing adrenal abnormalities, are reviewed, and the value of computed tomography, ultrasonography, radionuclide scintigraphy, and angiography are analyzed.
