Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest show a right PICC terminating in the upper SVC . In comparison to the prior exam on ___ , it may be slightly pulled back , although exact amount of change is difficult to tell based on differences in angulation and patient positioning . Basilar atelectasis is unchanged from the prior exam . Small focal opacity at the right lung base was not present on prior or on CT torso from ___ and most likely represents overlapping structures ; developing consolidation not excluded in the appropriate setting . No pleural effusion or pneumothorax . The cardiomediastinal silhouette is normal .
    OUTPUT:
    
1 . PICC in the upper SVC , possibly pulled back slightly from the prior exam , although evaluating for change is difficult giving different angulation of radiograph in patient positioning . 2 . Stable bibasilar atelectasis . Small focal opacity at the right lung base most likely represents overlapping structures ; developing consolidation not excluded in the appropriate clinical setting .
