Radiographic manifestations of transfusion-related acute lung injury.

OBJECTIVE The purpose of this article is to describe the clinical symptoms and illustrate the radiological manifestations of transfusion-related acute lung injury (TRALI) as the condition develops. We mention those findings that aid the discrimination from transfusion-associated cardiac overload. We will also point some of the characteristics that increase the risk of TRALI. CONCLUSION TRALI generally occurs within 1 to 2 h of the start of a blood transfusion. Though the radiographic features of TRALI are nonspecific, the diagnosis is established using clinical and radiological parameters. The diagnosis warrants a high index of suspicion as well as knowledge of its risk factors. There are no specific treatments; the best chance of survival in TRALI is with early diagnosis and prevention.
