Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube terminates at the orifice of right mainstem bronchus . An enteric tube passes far into the stomach . Evaluation of the chest is limited due to multiple overlying lines and tubes . Within this limitation , there are widespread interstitial opacities throughout the right lung with a basilar predominance as well as the left lung base . There is mild pulmonary vascular congestion and subtle Kerley B lines suggesting interstitial edema . A small right pleural effusion can not be excluded . No pneumothorax is detected on this semi-erect view . The cardiac silhouette is incompletely visualized in the setting of bibasilar opacities . The mediastinal contours are prominent due to tortuosity of the thoracic aorta with partial calcification of the aortic knob . Densities projecting over the right humerus and soft tissues of the upper arm are likely external to the patient .
    OUTPUT:
    
1 . Right mainstem intubation . Recommend re-positioning . 2 . Asymmetric pulmonary interstitial edema and vascular congestion on the right greater than the left . Superimposed infection can not be excluded in the appropriate clinical context .
