Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest redemonstrate marked asymmetric aeration of the right lung and architectural distortion related to prior right upper lobectomy , with posterior surgical rib defects . There is new hazy opacity involving the right lower lung with extension superiorly . Multiple air - fluid levels are present in the right upper lung in the resection bed , suggestive of complex loculated fluid , raising question of empyema . The left lung remains clear . The visualized portion of the cardiomediastinal silhouette is within normal limits . Trace subcutaneous emphysema is persistent , likely postoperative residual .
    OUTPUT:
    
1 . New hazy opacity involving the right lung with numerous air - fluid levels superiorly in the region of recent right upper lobectomy . This could represent infection with associated loculated fluid , however CT would be prudent to exclude empyema . 2 . No radiographic evidence of pneumothorax . 3 . Diminishing subcutaneous emphysema .
