Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest were obtained . Lung volumes are low and kyphotic angulation limits evaluation through the lower lungs . The heart is mildly enlarged . Prominent bronchovascular markings could reflect bronchovascular crowding , though the possibility of mild congestion is impossible to exclude . There is no frank pulmonary edema or definite signs of pneumonia . No large pleural effusion or pneumothorax is seen . The aorta appears unfolded . Bony structures are demineralized with deformity involving the left proximal humerus , partially imaged . Vertebroplasty changes in the thoracolumbar junction are better assessed on the concurrently performed L - spine radiograph .
    OUTPUT:
    
No signs of pneumonia . Equivocal signs of mild pulmonary congestion and mild cardiomegaly .
