Diffuse alveolar hemorrhage is a rare but serious pulmonary manifestation of systemic lupus erythematosus that may occur at some point during the course of disease. Pleuropulmonary complication of SLE that ranges from pleuritic pain to catastrophic alveolar hemorrhage can occur during the course of illness in 50% to 70% of affected individuals. A high index of suspicion is needed in patients of SLE with progressive clinical deterioration. An aggressive diagnostic approach and prompt immunosuppressive treatment is important to improve survival which otherwise carries a very high mortality rate.
