Transfusion-related acute lung injury (TRALI) is a serious complication following the transfusion of blood products. TRALI is under-diagnosed and under-reported because of a lack of awareness. TRALI occurs within 6 hours of transfusion in the majority of cases and its presentation is similar to other forms of acute lung injury. We report on the case of a 34-year-old pregnant woman who suffered from TRALI after transfusion during Cesarean section.
