Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear similar to the prior study . There is no definite pleural effusion or pneumothorax . Aside from improved aeration in the lateral right lower lung , more generally , multifocal opacities , the radiographic highlights of which are within the left upper and retrocardiac regions of the left lung , appear very similar to the prior examination . Right upper lobe opacities are probably similar but the findings seen on prior CT were not conspicuous radiographically .
    OUTPUT:
    
Persistent multifocal opacities . Follow - up of the prior findings worrisome for malignancy is recommended in the near future using chest CT , since it does not appear that CT findings including a large nodule in the right lung are well demonstrated on radiography .
