Adrenal venography in primary aldostero-nism. A, Typical leaflike pattern of the normal right adrenal venous drainage. B, In contrast, marked distortion of the normal venous anatomy by a relatively large (3-cm-diameter) adenoma of the left adrenal. Most solitary adenomas responsible for primary aldosteronism are smaller than 1 cm in diameter and thus usually cannot be seen using anatomic visualizing techniques.
