Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal silhouette is stable . Known left upper lobe mass is grossly stable . Left basilar opacity is seen with obscuration of the left hemidiaphragm which may be due to atelectasis ; however , underlying consolidation or disease spread is not excluded . The previously more focal right basilar opacity is less dense ; however , there continues to be patchy opacities in the right mid - to - lower lung which may be due to multifocal infection and / or mass suprahilar . Left costophrenic angle is blunted and a small left pleural effusion is not excluded . No evidence of pneumothorax is seen .
    OUTPUT:
    
Grossly stable cardiomediastinal silhouette with grossly stable known left suprahilar mass . Obscuration of left hemidiaphragm may due to underlying consolidation ; however , there may also be a possible pleural effusion and atelectasis . Right mid - to - lower lung opacities are less confluent as compared to the prior study ; however , remain concerning for infection .
