Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The presence of extensive subcutaneous emphysema reduces the sensitivity of chest radiography for detecting pneumothoraces . With this limitation in mind , no pneumothorax is identified . Left chest tube has been removed since the prior study , and right chest tube is unchanged in position . Endotracheal tube remains in standard position , but cuff appears slightly overdistended . Heart size is normal . Worsening heterogeneous airspace opacities in right lower lobe are concerning for aspiration or evolving infectious pneumonia . Numerous air - fluid levels are again demonstrated in the left upper lobe lateral to the left hilum , and may reflect hemorrhage or infection within a bullae . An adjacent area of consolidation is present in this region as well . As compared to the recent study of ___ , the degree of subcutaneous emphysema has worsened , and is particularly more marked in the neck , axilla and lateral chest wall as compared to the prior studies .
    OUTPUT:
    
1 . No evidence of pneumothorax following removal of left - sided chest tube , but extensive subcutaneous emphysema reduces the sensitivity of radiography for detecting pneumothoraces . 2 . Worsening right lower lobe airspace opacity , concerning for developing pneumonia in the appropriate clinical setting . 3 . Progressive diffuse subcutaneous emphysema . 4 . Severe emphysema .
