A 61-year-old woman developed atraumatic bilateral adrenal hemorrhages while on anticoagulation. CT and MRI scans demonstrated enlarged adrenals with typical hemorrhagic features. Sequential CT scans showed gradual resolution of adrenal enlargement. Four months after the bleed, PET/CT was d

Tuberculosis and other potentially treatable diseases remain important causes of adrenal insufficiency. Knowledge of the cause of adrenal destruction, although often difficult to ascertain clinically, is necessary for appropriate management. Clinical data are reviewed In eight patients with Addison's disease who underwent computed tomographic scanning and in 31 additional patients with Addison's disease in whom autopsy was performed. Seven of eight patients (87 percent) with tuberculous Addison's disease of no greater than two years' duration had enlarged glands whereas patients with longer duration of disease had smaller or normal-sized glands. Adrenal enlargement was also found in five of six (87 percent) subjects with carcinomatous replacement of the adrenal glands. The adrenal glands were small or undetectable in each of 16 patients with idiopathic Addison's disease. Adrenal calcification was found in nine of 17 (53 percent) tuberculous patients and was not found in any of the 22 other patients. Duration of adrenal disease, adrenal size on computed tomographic scanning, and presence of adrenal calcification were useful clues to the cause of Addison's disease.
