Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Dense left mid lung airspace opacification may represent a superior subsegment left lower lobe pneumonia or parenchymal mass . Nodular densities project over the lungs bilaterally consistent with pleural plaques related to prior asbestos exposure . There is mild pulmonary vascular congestion with trace pulmonary edema . There is probably a small right pleural effusion . There is no pneumothorax . Cardiomegaly is mild to moderate . The cardiomediastinal silhouette is otherwise unremarkable . Bilateral glenohumeral degenerative changes are partially assessed .
    OUTPUT:
    
1 . Left midlung airspace opacification may represent acute pneumonia or a parenchymal mass . Should be evaluated by chest CT if not recently performed . 2 . Mild volume overload including pulmonary vascular congestion , trace edema , and likely a small right pleural effusion . 3 . Extensive pleural plaques consistent with prior asbestos exposure .
