Pulmonary edema in a pediatric cancer patient after anesthetic induction.

Negative pressure pulmonary edema (NPPE) in the context of anesthesia is a rare condition, although pediatric patients are at higher risk. This case stands out for the severe respiratory clinic that quickly developed in a child with a cancer history whose radiological and clinical presentation suggested multiple differential diagnoses, including tumor recurrence with metastasis or pulmonary tuberculosis. NPPE is a well-described, but a probably underrecognized clinical syndrome, that occurs after intense inspiratory effort against an obstructed airway. In clinical practice, when unexplained pulmonary edema takes place, NPPE should be considered in the differential diagnosis. NPPE usually has a favorable prognosis but pediatricians, radiologists, and anesthesiologists should be aware of this complication.
