Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval removal of a nasoenteric catheter . A right internal jugular approach central venous catheter terminates at the cavoatrial junction or just below . A peritoneal drain terminates in the left upper quadrant , unchanged from prior . Multiple surgical clips are seen in the region of the epigastrium . A thoracic spine epidural catheter is in unchanged position . Bibasilar opacities likely reflect atelectasis . Lung volumes are low , though no confluent consolidation is identified . There is a rounded well - circumscribed lucency in the medial left lung apex just superior to the aortic knob . The position and morphology are suggestive of air in the esophagus , though follow - up radiograph is recommended to exclude progression . There is no large pleural effusion . No pulmonary vascular congestion or interstitial edema is identified . There is mild blunting of bilateral costophrenic angles suggestive of small effusion , unchanged .
    OUTPUT:
    
1 . Right central venous catheter terminating at the cavoatrial junction or just below . 2 . Persistent bibasilar atelectasis with probable small bilateral pleural effusions . 3 . Rounded lucency in the medial left lung apex . Findings likely represent air in the esophagus , though follow - up portable radiograph and dedicated PA and lateral chest radiographs when possible are recommended to exclude pneumomediastinum .
