Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Exam is slightly limited by patient rotation . Previously demonstrated left PICC is no longer visualized . Cardiac and mediastinal contours are unchanged with tortuosity of thoracic aorta again noted . Pulmonary vasculature is not engorged . Patchy opacity in the right lung base appears slightly improved , likely reflective of residual aspiration . Small right pleural effusion also appears resolved compared to the prior study . No pneumothorax is appreciated . Degenerative changes of the right AC joint are again noted .
    OUTPUT:
    
Interval removal of the left PICC . Improvement in the right basilar patchy opacity likely reflective of chronic aspiration with resolution of previously noted small right pleural effusion .
