Bilateral adrenal enlargement in Addison's disease caused by tuberculosis. Nephrotomographic demonstration.

Nephrotomography showed markedly enlarged adrenal glands in a 67-year-old man with acute Addison's disease due to tuberculosis. Other causes of acute adrenal insufficiency associated with enlarged adrenals are histoplasmosis and, rarely, bilateral metastatic carcinoma, amyloidosis, or hemorrhage. Radiologic demonstration of large adrenal glands in a patient with acute Addision's disease should strongly suggest an infectious etiology.
