[Differential diagnosis of pulmonary infiltration after insertion of a chest tube for pneumothorax].

Reexpansion injury of the lung is rare and may occur after reexpansion of a collapsed lung such as after evacuation of a large amount of air or fluid from the pleural space. Its pathogenesis, however, is not clearly understood. Pulmonary edema should always be considered if the patient's respiratory condition worsens after lung reexpansion.
