    INPUT: The heart size is enlarged and there is no evidence of vascular congestion . The hilar and mediastinal contours are normal . Increased opacification at the left lung base is consistent with volume loss in the lower lobe and effusion . There is an increased opacification at the right lower lobe , seen in the frontal view but not appreciated on the lateral view . There is a small right pleural effusion .
    OUTPUT:
    
1 . Cardiomegaly with no vascular congestion raises the possibility of underlying cardiomyopathy or pericardial effusion . 2 . Increased density in right lower lobe , not appreciated on the lateral view . In the appropriate clinical setting , may suggest pneumonia .
