Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest are compared to previous CT abdomen from ___ and chest x-ray from ___ . Linear opacities at the left lung base suggest atelectasis . Slight increased focal opacity at the right lung base laterally could potentially also be due to atelectasis ; however , acute infection is also possible . Increased density at the right cardiophrenic angle is compatible with previously identified prominent epicardial fat . Blunting of the right latter costophrenic angle may be due to small effusion or atelectasis in this region . Cardiomediastinal silhouette is stable , as are the osseous and soft tissue structures .
    OUTPUT:
    
Bibasilar opacities , potentially due to atelectasis ; however , subtle increased opacity at the right lung base may be due to infection . Clinical correlation is recommended .
