Fifteen consecutive patients with metastatic carcinoma who demonstrated bilateral adrenal metastasis on abdominal computed tomography (CT) were evaluated by the cosyntropin challenge test. Primary sites of tumors included lung, ten; colon, two; gastric, one; ovarian, one; and unknown primary, one. Bilateral adrenal enlargement was defined as greater than 1 cm on CT scan. ⋯ Of the clinical parameters evaluated, all five patients had nausea, anorexia, and orthostatic hypotension. The clinical onset of adrenal insufficiency was insidious; no patient experienced acute adrenal crisis. We conclude that adrenal insufficiency is not a rare occurrence in patients with metastatic cancer and bilateral adrenal involvement on CT scan.
