Adrenal incidentalomas are adrenal masses detected during radiologic examination performed for an indication otherthan evaluation of adrenal disease. Diagnosis of these masses has increased due to the widespread use of ultrasonography, computed tomography (CT) and magnetic resonance imaging. We report the case of a 69-year-old woman with a left adrenal incidentaloma simulating a non-functioning adenoma and right adrenal atrophy. The results of contrast-enhanced CT and subsequent histopathological study confirmed the diagnosis of adrenal tuberculosis. Hormonal study revealed partial adrenal insufficiency as a result of bilateral involvement of the adrenal tuberculosis.
