Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A device is again noted in the left hemi thorax with wires coursing toward the neck , which may represent a deep nerve stimulator . The inspiratory lung volumes remain low . On this single view , there is no focal consolidation concerning for pneumonia . Bibasilar opacities are most compatible with atelectasis in the setting of low lung volumes although potentially pneumonia or aspiration in the left mid to lower lung . No large pleural effusion or pneumothorax is present . The cardiac silhouette is accentuated by low lung volumes but likely within normal limits . The mediastinal and hilar contours are within normal limits and unchanged .
    OUTPUT:
    
Patchy basilary opacities which are non-specific , increased ; with low lung volumes atelectasis is perhaps most likely , but pneumonia and aspiration are additional potential etiologies . Standard PA and lateral radiographs with good inspiration might be helpful for short - term follow - up if practical .
