    INPUT: Lung volumes remain low . This accentuates the size of the cardiac silhouette which is mildly enlarged . Mediastinal and hilar contours are unchanged , without evidence for pneumomediastinum . There is continued bulging of the right lower mediastinal contour , possibly reflective of residual right paraesophageal fluid . Pulmonary vasculature is normal . Linear opacities within the right lung base are compatible with subsegmental atelectasis . No focal consolidation , pleural effusion or pneumothorax is identified . No subdiaphragmatic free air is seen . Clips are re - demonstrated at the gastroesophageal junction .
    OUTPUT:
    
Right basilar subsegmental atelectasis . No evidence for pneumomediastinum or subdiaphragmatic free air .
