Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP upright view of the chest was provided . There is again noted to be post - surgical change of the left lung apex with volume loss and leftward retraction of the mediastinal structures . There is also evidence of prior left upper rib cage resection with chest wall deformity evident . The right lung is hyperinflated with upper lobe lucency , likely reflecting underlying emphysema . Coarsened interstitial markings with micronodular opacity in the right lower lung likely reflect scarring and appears stable from prior exam . The left CP angle is excluded thus limiting evaluation . No definite new consolidation in the left lung to suggest the presence of pneumonia . The heart size appears stable .
    OUTPUT:
    
Post - surgical changes in the left upper chest , with no definite signs of pneumonia .
