CXR completed at time of presentation reveals bilateral airspace disease (a). Coronal CT chest images completed at the same time reveal bilateral, predominantly central, heterogeneous groundglass opacities, involving both upper and lower zones with subpleural sparing (b). These opacities quickly resolved upon treatment with high-dose corticosteroids and IV cyclophosphamide (c).

Computed tomography of the chest identified bilateral groundglass opacities (Figure 1).
First (left) and second (right) sequential aliquots obtained from bronchoalveolar lavage. Serial returns are progressively hemorrhagic.

Sequential bronchoalveolar lavage aliquots became progressively more hemorrhagic with microscopic evidence of hemosiderin-laden macrophages, suggesting diffuse alveolar hemorrhage (Figure 2).
