Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well expanded . The right lung is clear . In the lateral view there is an ill - defined opacity blunting the costophrenic angle without a clear fluid meniscus to account for pleural effusion in this side . There is no pleural effusion in the right either . There is no pneumothorax . With the exception of stable moderate cardiomegaly and minimal aortic tortuosity , the cardiomediastinal and hilar contours are unremarkable .
    OUTPUT:
    
Probable consolidation in the left lower lobe only seen in the lateral view might represent atelectasis although a focus of pneumonia can not be excluded .
