    INPUT: There is significant leftward rotation of the patient on current radiograph . Allowing for changes due to this , the cardiomediastinal silhouette is unchanged from same - day outside hospital chest radiograph . Extensive left lung opacification limits full evaluation of the cardiac silhouette , which appears normal . There is no evidence of pulmonary vascular congestion or pulmonary edema . Extensive consolidation with air bronchograms involving the majority of the left lung is concerning for pneumonia . More ill - defined reticular opacities within the right lower lung may reflect sequela of aspiration or pneumonia . Underlying emphysema is suspected . There is no right pleural effusion . There is likely at least a moderate left pleural effusion . There is no pneumothorax .
    OUTPUT:
    
Extensive left lung opacification concerning for pneumonia . Right lower lung reticular opacities may reflect aspiration or pneumonia . Probable moderate left pleural effusion . Recommend followup to resolution .
