Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are mildly hypoinflated . No pleural effusion although slightly limited evaluation due to limited view of the right costophrenic angle on frontal projection . No pneumothorax . Heart size , mediastinal contour , and hila are unremarkable . Subtle increase in hyperdense area on lateral projection just superior to the a costophrenic angles . Limited assessment of the upper abdomen is within normal limits and visualized osseous structures are unremarkable .
    OUTPUT:
    
No definite evidence of pneumonia . A density on lateral view at posterior costophrenic sulcus is felt likely projectional . However , recommend repeat radiography in short interval after resolution of symptoms to ensure resolution of this density .
