    INPUT: Cardiac silhouette size remains mildly enlarged . The mediastinal and hilar contours are unchanged , with similar prominence of the hila bilaterally . Pulmonary vasculature is not engorged . The lungs are hyperinflated with emphysematous changes again noted . Sutures from prior wedge resection is visualized in the left upper lung field . 4 cm cavitary lesion within the left apex appears relatively unchanged . Residual patchy opacity is seen within the right lung base , which appears improved , however worsening ill - defined opacities are seen within the left mid lung field . Previously seen consolidative opacity in the left lower lobe may be slightly improved in the interval . Small left pleural effusion is likely present . There is no pneumothorax .
    OUTPUT:
    
1 . Worsening patchy ill - defined opacities in the left mid lung field concerning for pneumonia . 2 . Residual patchy opacity in the right lung base which may reflect an area of resolving infection or continued but improved infection . 3 . Previously noted area of consolidation in the left lower lobe appears somewhat improved . Small left pleural effusion likely present . 4 . Unchanged cavitary lesion in the left apex .
