    INPUT: The lungs are relatively hyperinflated . No focal consolidation is seen . No pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal to mildly enlarged . The aorta is tortuous . There is slight prominence of the superior mediastinum which may be due to AP technique and prominent vasculature . If clinical concern for acute mediastinal or spinal process , CT is more sensitive and should be considered .
    OUTPUT:
    
No focal consolidation to suggest pneumonia . Slight prominence of the superior mediastinum which may be due to AP technique and prominent vasculature . No prior for comparison to assess chronicity . If clinical concern for acute mediastinal or spinal process , CT is more sensitive and should be considered .
