Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Interval removal of endotracheal tube and nasogastric tube . Heart size is normal . Upper lobe predominant emphysema is present , as well as a large thin - walled cystic structure within the left retrocardiac region , which may be due to a bulla or pneumatocele . This was previously imaged on abdominal CT of ___ and appears relatively similar allowing for technical differences . Worsening heterogeneous opacities are present in the right lower lobe , and there are also poorly defined nodular opacities in the right lung apex . A focal patchy opacity is also present in the left retrocardiac area . These findings are nonspecific , but could reflect evolving multifocal pneumonia or multifocal aspiration in the appropriate clinical setting . Linear atelectasis is present in both the left mid and right lower lung . Additional right lower lung septal lines may due to asymmetrical edema in the setting of small right pleural effusion and peribronchial cuffing .
    OUTPUT:
    
Multifocal lung opacities , possibly due to multifocal aspiration and mild edema . When the patient 's condition permits , standard PA and lateral chest radiographs are recommended for more complete evaluation of the chest , especially to reevaluate nodular opacities in the right apex .
