Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is in place with tip 3 .4 cm above the carina . An enteric tube extends inferiorly with side port in the stomach . A right internal jugular approach central venous catheter has tip in the mid SVC . Prominent mediastinal contour with widening likely represent a combination of vascular engorgement and underlying mediastinal lymphadenopathy compatible with lymphoma . Although mediastinal hematoma is not excluded status post new central line placement , lack of tracheal deviation makes this less likely . The cardiac silhouette is prominent . The lung volumes are low , with new interval development of a moderate left pleural effusion and dense retrocardiac opacity compatible with atelectasis . The right lung is relatively clear . A rounded density in the left supraclavicular soft tissues measures at least 5 .2 x 4 .4 cm , upon correlation with prior CT dated ___ , consistent with a large centrally necrotic nodal mass .
    OUTPUT:
    
1 . Lines and tubes appropriate in position . 2 . New moderate left pleural effusion with compressive atelectasis . 3 . Upper mediastinal widening compatible with a combination of vascular engorgement and underlying adenopathy . 4 . Dominant left supraclavicular nodal mass .
