Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest . Low lung volumes are again noted . There is an asymmetric right basilar opacity which is also seen on the lateral view . Given the low lung volumes this may be due to atelectasis however an infection is not completely excluded . The right midlung nodular opacity is again seen in different location when compared to prior , now no longer overlying the same rib and may represent a calcified granuloma . Elsewhere the lungs are clear and there is no effusion . The cardiomediastinal silhouette is within normal limits . No acute osseous abnormality is detected .
    OUTPUT:
    
Faint right basilar opacity potentially due to atelectasis given the low lung volumes noting that infection is not excluded .
