Which radiographic finding is typical for TRALI on chest imaging?

• A. Unilateral infiltrate
• B. Cardiomegaly without edema
• C. No edema
• D. Bilateral pulmonary edema

Answer: (D)

TRALI causes acute noncardiogenic pulmonary edema after a transfusion. On chest radiographs you’d expect to see diffuse bilateral infiltrates, reflecting fluid leakage into the lungs from capillary injury, often with a normal heart size. This bilateral edema pattern fits TRALI best, whereas unilateral infiltrates suggest localized processes like pneumonia or aspiration, no edema contradicts the edema feature, and cardiomegaly would point toward cardiogenic edema rather than the noncardiogenic edema typical of TRALI.
