As a Rare Reason of Alveolar Consolidation, Negative Pressure Pulmonary Edema: Case Report.

In this paper we describe two cases with negative pressure pulmonary edema (NPPE). Excessive negative airway pressures against an obstructed airway has been reported to cause fluid filtration into alveoli and lung edema. The patients are generally young adults without any medical problems. The condition involves central interstitial area of both lungs and is treated by nonnvasive mechanical ventilation and corticosteroids.
