Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . The mediastinal and hilar contours are normal . The pulmonary vasculature is normal . Left lower lobe consolidation is large . No pleural effusion or pneumothorax . Approximately 4 cm curvilinear density in the anterior heart seen on the lateral view was seen previously and most likely represents dystrophic calcification in the left ventricle subsequent to myocardial infarction . The remainder of the curved opacity posterior to this curvilinear density is likely due to superimposition of multiple structures and is likely nonspecific .
    OUTPUT:
    
Left lower lobe pneumonia .
