Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient is rotated somewhat to the right . There are relatively low lung volumes . Left hilar prominence may be due to vascular congestion although underlying lymphadenopathy , pulmonary consolidation , or other pulmonary lesion is not excluded . Reticular nodular opacities at the lung bases are nonspecific but could be due to small airways disease . There is also additional more focal left base retrocardiac opacity ; differential diagnosis includes pneumonia although underlying pulmonary mass is not excluded . No large pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal . Mediastinal contours are grossly unremarkable . Chronic deformity at the partially imaged right glenohumeral joint .
    OUTPUT:
    
Prominent left hilum is nonspecific , underlying lymphadenopathy , consolidation , or pulmonary lesion not excluded . Left base retrocardiac opacity could be due to pneumonia , underlying other pulmonary lesion not excluded . Bibasilar subtle reticulonodular opacities may be due to small airways disease . Consider dedicated PA and lateral views of the chest or CT for better evaluation .
