Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . Mediastinal and hilar contours are unremarkable . Pulmonary vascularity within the right lung is a more pronounced compared to the left , findings which could suggest mild asymmetric pulmonary edema . Patchy opacity in the right lung base may reflect atelectasis . Minimal blunting of the right costophrenic angle suggests a trace pleural effusion , and there is minimal fluid seen in the right minor fissure . No large left pleural effusion is seen , but the left costophrenic angle is excluded from the field of view . There is no pneumothorax . Vascular stent is noted in the right the brachial / axillary region .
    OUTPUT:
    
Trace right pleural effusion and possible asymmetric mild pulmonary edema . Patchy right basilar opacity , potentially atelectasis . Infection is not excluded in the correct clinical setting .
