Diffuse alveolar hemorrhage is known to be a devastating clinical condition with myriad etiologies. The immediate post-transplant period is plagued by immunosuppression, surgical complications, and nosocomial sources of infection. Diffuse alveolar hemorrhage in this setting is usually attributed to infection. In this case report, an unusual cause of diffuse alveolar hemorrhage due to anti-thymocyte globulin used as an induction agent is described, and an approach to DAH in the immediate post-transplant setting is discussed.
