Alveolar infiltrates on chest radiograph, dyspnea, anemia, hemoptysis and, occasionally, fever are characteristic. Rapid clearing of diffuse lung infiltrates within 2 days is a clue to the diagnosis of diffuse alveolar hemorrhage (eFigure 9–25). Pulmonary hemorrhage can be associated with an increased single-breath diffusing capacity for carbon monoxide (DLCO), although this test is infrequently obtained. Sequential BAL on bronchoscopy is the preferred method for diagnosis. Diffuse alveolar hemorrhage is confirmed when lavage aliquots are progressively more hemorrhagic.
