CTICasesNegative Pressure Pulmonary Edema Secondary to Laryngospasm
Imaging findings
Chest radiograph demonstrates diffuse, bilateral alveolar opacities and mild cardiomegaly in a patient who recently underwent extubation. The patient quickly recovered and was discharged without intubation.
Key takeaways
Negative pressure pulmonary edema is a form of noncardiogenic pulmonary edema that classically occurs after post-extubation laryngospasm in the recovery room. The extreme negative intrathoracic pressure generated by strong inspiratory efforts against a closed glottis causes a rapid hydrostatic fluid shift into the alveoli, which typically resolves rapidly with conservative care.
