Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low leading to crowding of the bronchovascular structures . Bilateral diaphragmatic eventration is unchanged from the prior examination . Left lower lobe retrocardiac atelectasis is noted . Asymmetrical opacity overlying the first costochondral junction is present . The right lung and upper left lung are otherwise grossly clear . There is no large pleural effusion identified . The cardiomediastinal silhouette is grossly within normal limits . Diffuse idiopathic skeletal hyperostosis is noted involving the visualized thoracic spine .
    OUTPUT:
    
1 . Low lung volumes and left retrocardiac atelectasis . No acute cardiopulmonary process . 2 . Asymmetric opacities noted overlying the first costochondral junction . Findings may be degenerative in nature , although an overlying pulmonary nodule can not be excluded . Recommend apical lordotic views for further assessment .
