Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP portable views of the chest are obtained . There is severe thoracolumbar scoliosis . Areas of bibasilar patchy opacity are seen , which could be due to underlying infection and / or aspiration . There are also areas of scarring / atelectasis in the upper lobes bilaterally . No prior is available for comparison . The cardiac silhouette is not enlarged . The mediastinal and hilar contours are unremarkable . There is no left pleural effusion . Slight blunting of the right costophrenic angle may be due to overlying soft tissue , although a trace pleural effusion would be difficult to exclude . There are degenerative changes at the bilateral shoulder joints , right greater than left , not fully evaluated .
    OUTPUT:
    
Patchy bibasilar opacities could be due to chronic aspiration , although underlying infectious process is not excluded . Bilateral upper lobe areas of linear atelectasis / scarring .
