Evaluation of the mediastinal and hilar contours is limited by rotation though there is no gross abnormality . There is no pneumothorax .
    OUTPUT:
    
Stable pulmonary edema . Allowing for significant leftward rotation of the patient left lower lobe opacity is stable to minimally improved possibly reflecting pleural effusion and / or atelectasis . However in the right clinical setting persistent pneumonia is not excluded . If clinically indicated a CT of the chest may be obtained .
