Adrenal hemorrhage: a complication of anticoagulant therapy--a case history.

A seventy-five year-old woman developed adrenal hemorrhage and acute adrenal insufficiency while receiving anticoagulant therapy. Abdominal CT scan was consistent with bilateral adrenal hemorrhage and was an important contribution to diagnosis and therapy. Acute adrenal hemorrhage should be suspected in patients, especially the elderly, who have recently begun anticoagulant therapy and develop upper abdominal pain followed by decreased sensorium, high fever, hypotension, and hyponatremia. Any consideration of the diagnosis of sepsis with shock in a recently anticoagulated elderly hospital patient should suggest the possibility of acute adrenal hemorrhage. Abdominal CT scan and a cosyntropin stimulation test should be performed to confirm the diagnosis. Failure of diagnosis has generally been associated with death in most patients, whereas prognosis in patients treated with corticosteroids is excellent.
