Primary aldosteronism and adrenal incidentaloma.

Adrenal incidentaloma are usually found during the assessment of non adrenal disease. In this paper we report the association between a bilateral adrenal hyperplasia and a macronodule of adrenal cortex (adrenal incidentaloma) which is a rare and misleading cause of primary aldosteronism. In the light of this association even if it is likely to remain rare and of those previously published, its existence is an additional reason for suggesting surgical treatment of primary aldosteronism only to patients who satisfy the following criteria: 1) satisfactory control with spironolactone; 2) poor spironolactone tolerance and poor control with other drugs; 3) accept to be operated on and the risk of a possible error.
