    INPUT: PA and lateral views the chest were provided . Lung volumes are markedly low limiting assessment . Extensively sclerotic appearance of the bony structures compatible with metastatic disease again noted which somewhat limits the assessment of the underlying lungs . Allowing for this , no overt signs of pneumonia or edema . No large effusion or pneumothorax . Cardiomediastinal silhouette appears grossly stable with a top - normal heart size . No definite acute fracture .
    OUTPUT:
    
Diffuse osseous metastatic disease . No overt evidence for pneumonia or edema on this limited exam .
