    INPUT: Low lung volumes account for some degree of bronchovascular crowding . Vague opacities in both lung bases may be due to underinflation and summation of structures given superimposition of multiple ribs , although pneumonia can not be completely excluded . There is no pleural effusion or pneumothorax . The cardiomediastinal contour is unchanged . Spinal hardware is also stable without evidence of hardware - related complications .
    OUTPUT:
    
LOWER LUNG VAGUE OPACITIES EQUIVOCAL FOR EARLY PNEUMONIA .
