Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size appears normal . The mediastinal contours are grossly unremarkable . Prominence of both hila may reflect underlying lymphadenopathy . Extensive nodular opacities are noted diffusely in both lungs , but particularly within the lung periphery . More focal opacity within the right lung base could reflect an area of infection . No pneumothorax or pleural effusions . Mild pulmonary vascular congestion is also likely present . Gaseous distention of colonic loops of bowel in the left upper quadrant are demonstrated .
    OUTPUT:
    
Diffuse nodular opacities in both lungs concerning for widespread metastatic disease . More focal opacity in the right lung base could reflect an area of developing infection . Probable mild pulmonary vascular congestion . Correlation with any previous imaging or history of malignancy is recommended , and if there is no recent chest CT performed or known diagnosis of metastatic disease , a chest CT should performed .
