We studied an asymptomatic 55-year-old man who was found to have markedly enlarged adrenal glands on an abdominal computed tomographic scan and was scheduled to have adrenal biopsy because of suspicious findings on an adrenal magnetic resonance image. However, hormonal studies revealed congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Treatment with dexamethasone decreased the size of the adrenal glands. This is, we believe, the first report of congenital adrenal hyperplasia in an adult, diagnosed during the evaluation of an incidental adrenal lesion. Although congenital adrenal hyperplasia can present with varying severity and remain undiagnosed into adulthood, it is usually not considered in the evaluation of asymptomatic adult adrenal masses. We emphasize the need for proper hormonal studies in the evaluation of incidental adrenal lesions.
