Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The right - sided PICC line has been retracted and now terminates at the level of the mid clavicular line along the expected course of the right subclavian vein . The heart is mild - to - moderately enlarged with left ventricular configuration . The mediastinal and hilar contours appear unchanged . Persistent band - like opacities in the left mid lung suggest minor atelectasis or scarring . There is a patchy new nonspecific opacity in the right lower lung , although suggestive of minor atelectasis . Developing pneumonia is difficult to exclude , however . There is no pleural effusion or pneumothorax . Severe degenerative changes involving the right shoulder are partly visualized .
    OUTPUT:
    
1 . Retraction of PICC line , which now terminates in the mid subclavian vein . 2 . Patchy right basilar opacity , although compatible with minor atelectasis . The possibility of developing pneumonia is not entirely excluded , however , and short - term followup radiographs could be considered if symptoms were to persist or worsen .
