Annals of Cardiac Anaesthesia. 2014 Apr; 17(2): 161-163.http://imsear.searo.who.int/handle/123456789/150320A 3‑month‑old male child underwent uneventful inguinal herniotomy under general anesthesia. After extubation, airway obstruction followed by pulmonary edema appeared for which the baby was reintubated and ventilated. The baby made a complete recovery and extubated after about 2 h. A post‑operative computed tomography scan revealed a posterior mediastinal cystic mass abutting the tracheal bifurcation. Presumably, extrinsic compression by the mass on the tracheal bifurcation led to the development of negative pressure pulmonary edema.enLung cystNegative pressure pulmonary edemaPosterior mediastinal massAirway Extubation --adverse effectsAnesthesia, General --adverse effectsHumansInfantMaleMediastinal Cyst --classificationMediastinal Cyst --complicationsPulmonary Edema --diagnosisPulmonary Edema --etiologyTomography, X-Ray ComputedArticle
