    INPUT: There has been interval placement of a left basilar chest tube . Small residual pneumothorax seen surrounding the left lung apex . There has been interval re-expansion of the left lower lobe with some parenchymal opacity , potentially residual atelectasis although given older prior , improving infection is also possible . Wedge - shaped right upper lung opacity laterally is unchanged and as previously detailed potentially representing an infarct . Small right pleural effusion is visualized . Chronic underlying changes of the lungs appears similar compatible with patient 's underlying emphysema .
    OUTPUT:
    
Interval placement of a left basilar chest tube with decrease in size of the left - sided pneumothorax which persists surrounding the left lung apex . Other changes as above notable for re-expansion of left lower lobe with some persistent opacity for which followup to resolution is necessary . Wedge shaped right upper lung opacity for which CTA is again recommended .
