A case of type I postobstructive pulmonary edema in a child after expulsion of a foreign body

ABSTRACT Postobstructive pulmonary edema, also known as negative pressure pulmonary edema, is a rare condition associated with upper airway obstruction. In its acute form, it is secondary to inspiratory efforts against an obstructed airway (for example, a foreign body) and occurs at the time or after the relief of the obstruction. It usually resolves spontaneously within a few hours or days, but in rare cases, it can be life-threatening and require intensive care. We report the case of a child with a rare case of pulmonary edema diagnosed after the expulsion of a tracheal foreign body: a cherry tomato. Pediatrician and pediatric radiologists should be aware of this complication to avoid unnecessary further investigations and inappropriate treatments.
