Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal silhouette is within normal limits . The bilateral hila are unremarkable . Linear opacities near the left lung base are probably platelike atelectasis . More diffuse airspace in the right lower lung medially obscuring the right heart border may represent atelectasis , developing infection or sequelae of aspiration , or possibly small pulmonary contusions in the setting of recent trauma . Otherwise , the lungs are clear . There is no evidence of pulmonary vascular congestion . There is no pneumothorax or pleural effusion .
    OUTPUT:
    
1 . Right lower lung consolidation , either pneumonia , aspiration , or possibly pulmonary contusions from recent trauma . 2 . Left lower lung platelike atelectasis . 3 . No evidence of displaced rib fracture . Note , chest x-ray is not sensitive for the detection of subtle or nondisplaced rib fractures .
