No pneumothorax . Allowing for low lung volumes , the cardiac silhouette is likely top normal in size . The mediastinal contours are prominent due in part to low lung volumes and unfolding of the thoracic aorta . The trachea is mildly deviated to the right by the aortic knob . The visualized upper abdomen is relatively gasless with a density projecting over the left upper quadrant , which is of uncertain etiology . Deformity of several right lateral ribs likely represents old healed rib fractures .
    OUTPUT:
