A dedifferentiated large posterior mediastinal liposarcoma – An incidental finding successfully resected

This is a case of a posterior mediastinal mass in an asymptomatic gentleman, which was resected successfully and he has been disease free for more than a year of follow up. The histopathology findings happen to be a rare occurrence.

Post extubation negative pressure pulmonary edema due to posterior mediastinal cyst in an infant.

A 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.
