Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The study is somewhat limited secondary to positioning . The patient is markedly rotated . Again seen is a large - bore dual - lumen catheter from a left subclavian approach . Elevation of the right hemidiaphragm is again evident and slightly exaggerated . There is engorgement of the vascular pedicle and cephalization of the pulmonary vascularity , which is likely at least in part due to the supine positioning . Linear atelectasis is seen in the retrocardiac left lower lobe . No focal consolidation is seen . The mediastinum again demonstrates a tortuous aorta exaggerated by the rotation . Likewise , the cardiac silhouette is stable , but exaggerated . No large effusion is noted . Blunting of the right costophrenic angle is relatively stable . There is no pneumothorax .
    OUTPUT:
    
Limited study , but overall grossly stable . The slight engorgement is noted principally in the left hilar region may be in part due to recumbency .
