Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: When compared to prior , the previously seen tubing presumably from VP shunt along the right chest wall is no longer visualized . Streaky bibasilar opacities more so on the right are suggestive of atelectasis . There is blunting of the posterior left costophrenic angle potentially due to small effusion or pleural thickening . There is no acute confluent consolidation . The cardiomediastinal silhouette is within normal limits . No acute osseous abnormality is detected .
    OUTPUT:
    
Linear opacities most suggestive of atelectasis . Possible trace left pleural effusion versus pleural thickening . Previously seen VP shunt catheter along the right chest wall is no longer visualized .
