CT localization of an aldosteronoma in a 10-year-old boy.

Primary aldosteronism in children under 16 years of age is usually due to adrenal hyperplasia. We could find only seven cases in the literature where it was caused by a solitary adrenal adenoma; all but one were female. We describe the case of a 10-year-old Caucasian boy in whom a unilateral adrenal adenoma was demonstrated by high resolution computed tomography (CT) alone. The literature is reviewed.
