Progression of chest radiograph abnormalities with alveolar hemorrhage in a patient with systemic lupus erythematosus

Chest radiographs in a patient with SLE showing progression of alveolar hemorrhage.
(A) Chest radiograph at the time of the initial bleed, showing alveolar and parenchymal opacities, which are commonly seen with alveolar hemorrhage.
(B) Repeat chest radiograph 1 day later, showing complete "white-out" of the right lung and increased opacities on the left.
