    INPUT: A right internal jugular approach central venous catheter is in place with tip terminating at the cavoatrial junction . A metallic vascular stent is seen projecting superior to the aortic knob which is calcified . Multiple postsurgical changes are present within the lungs , including chain sutures within the righ upper lobe , presumably from prior lobectomy , as well as mediastinal clips in this area . Within the left lung , there is a spiculated mass within the upper lobe , as well as pleural thickening and a large left pleural effusion which obscures the left heart border . Within the right lung , there is perihilar indistinctnes , reflecting mild pulmonary edema . Note is made of surgical clips within the left neck as well . There is slight tracheal deviation , possibly due to enlarged thyroid .
    OUTPUT:
    
1 . Left upper lobe opacity could conceivably be due to loculated pleural fluid , although given spiculated appearance , a solid mass is likely , and CT should be performed for further characterization . 2 . Mild pulmonary edema and left pleural effusion .
