    INPUT: PA and lateral views of the chest were provided . There is a similar overall pattern of vague ground - glass opacities within both lungs which has been previously ascribed to pulmonary edema and again the possibility of pulmonary edema is raised .

No pneumothorax . Bony structure is intact . Metallic coils in the upper abdomen noted . A sclerotic appearance of the spine is again noted .
    OUTPUT:
