    INPUT: PA and lateral views of the chest . When compared to prior , there has been no change . Again seen is hazy opacity obscuring the right heart border which on the lateral view is compatible with right middle lobe atelectasis . Elsewhere , the lungs remain clear . Cardiomediastinal silhouette is within normal limits . No acute osseous abnormality detected .
    OUTPUT:
    
Persistent right middle lobe opacity suggestive of atelectasis with similar configuration . No new consolidation . Given the persistent volume loss , CT scan should be considered to look for obstructing lesion in the airway .
