    INPUT: Opacity at the right cardiophrenic angle is compatible with a prominent fat pad . Calcified granulomas in the right middle lobe seen on prior CT are faintly visualized . There is some associated linear opacity at the right lung base as well , unchanged from prior potentially due to atelectasis . Elsewhere , lungs are clear . The cardiomediastinal silhouette is within normal limits . No acute osseous abnormalities .
    OUTPUT:
    
Unchanged right basilar opacity . Potentially atelectasis noting that infection can not be entirely excluded .
