Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable view of the chest . Moderate mid to lower thoracic dextroscoliosis is noted . There is also apparent fusion of several thoracic vertebral bodies . There is secondary asymmetry of the thoracic cavities . Dense left basilar opacity could represent secondary atelectasis due to the bony changes although underlying effusion or consolidation is also possible . The right lung is grossly clear . Cardiomediastinal silhouette is difficult to assess . Chronic changes seen in the proximal left humerus presumably from prior fracture .
    OUTPUT:
    
Chronic bony thoracic osseous changes with asymmetry of the thoracic cavities . Left basilar opacity could be secondary to atelectasis given these findings although underlying effusion or consolidation is possible . Additional imaging would be necessary to further assess . Older exams should they become available , would be helpful .
