Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is slightly limited due to patient positioning . Heart size is mildly enlarged . Widening of the superior mediastinum appears to be due to mediastinal lymphadenopathy as seen on the previous CTA of the neck . Bilateral hilar enlargement also may be due to underlying lymphadenopathy . Mild pulmonary edema is present . Additionally there are scattered ill - defined nodular opacities throughout the lungs diffusely . A trace left pleural effusion may be present , but no large right pleural effusion is seen , however the right costophrenic angle is excluded from the field of view . There is no pneumothorax . No acute osseous abnormality is visualized . Remote fracture of the right clavicle is present .
    OUTPUT:
    
1 . Mild pulmonary edema . Trace left pleural effusion . 2 . Widened superior mediastinum and bilateral hilar enlargement likely due to underlying lymphadenopathy . 3 . Diffuse nodular opacities , as seen on the recent CTA , but not clearly well visualized . Findings which could suggest small airways infection , inflammation , or aspiration . Metastatic disease is not completely excluded .
