Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Evaluation is somewhat limited by overlying trauma board . An endotracheal tube terminates 2 .3 cm above the level of the carina . And oral gastric tube is seen terminating within the stomach . A left - sided central venous line terminates near the cavoatrial junction . There is a dual lead left pectoral pacemaker noted . Surgical clips are noted within the right upper abdomen . A vascular stent overlies the right upper lobe . The left lung is nearly completely opacified , obscuring the left cardiac border and left hemidiaphragm . A left pleural effusion can not be excluded . A vague opacity overlies the left lung apex , potentially concerning for underlying aortic injury . The right lung demonstrates mild basilar atelectasis and is otherwise grossly clear . There is no right pleural effusion . Heavy atherosclerotic calcification is seen within the aortic arch .
    OUTPUT:
    
1 . Focal opacity within the left apical lung . Findings are concerning for aortic injury in the setting of trauma , and CTA chest is recommended for further characterization . 2 . ET tube terminating 2 .3 cm above the carina . 3 . Near - complete left lung opacification may be secondary to collapse or dense consolidation . Left pleural effusion is not excluded .
