A case report of transfusion-related acute lung injury during plasma exchange therapy for thrombotic thrombocytopenia purpura.

Transfusion-related acute lung injury (TRALI) is a transfusion reaction that is often under recognized and underreported. Implications for diagnosis not only influence treatment considerations but also extend to donor selection, donor deferral and ultimately the safety of the final blood product. We report a case of a previously well 19-year-old female who presented a one week history of flu-like symptoms and mucosal bleeding.
