Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lordotic positioning . Again seen is mild cardiomegaly , with a calcified ascending aorta There is patchy relatively confluent opacity at the right lung base extending to the costophrenic sulcus . , new compared with ___ . No associated air bronchograms are identified , however . Elsewhere , no focal infiltrate or effusion . No CHF . Thin vertical linear lucency along the mid left chest wall is noted , new compared with the prior study . This may represent artifact due to out overlying soft tissues . An atypical pneumothorax along the left mid chest wall is considered less likely . No other evidence of pneumothorax . Probable old healed left sided rib fractures noted , unchanged .
    OUTPUT:
    
New confluent opacity at the right lung base , suspicious for a focal pneumonic infiltrate . A small associated effusion would be difficult to exclude . If clinically indicated , a lateral view could help for further characterization . Minimal , if any , left base atelectasis . No left base consolidation or effusion . Thin linear lucency abutting the inner surface of the left mid chest wall . Is there clinical concern for a pneumothorax in this location ? . This appearance is more suggestive of artifact due to overlying soft tissue planes . No other evidence of pneumothorax .
