MRCP2-4153

A 20-year-old woman presents with increasing breathlessness and hypoxia two days after being admitted for severe burns. She has no significant medical history, but her father had a heart attack at age 40. She is a non-smoker and has a respiratory rate of 26 breaths per minute and a pulse rate of 110 beats per minute. Crackles are heard over both lung fields on examination, and a chest x-ray shows bilateral hazy shadowing. What is the probable diagnosis?
