The computed tomographic (CT) findings in five patients with tuberculo
us Addison's disease were evaluated. All patients had extra-adrenal tu
berculosis. Two patients had enlarged adrenal glands with calcificatio
ns at the times of diagnosis. Follow-up CT from 4 to 30 months showed
a progressive decrease in the size of adrenal glands from bilateral en
largement to small calcified glands and provides a clue to the etiolog
y of Addison's disease and proper therapy.
