Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Opacity at the right lung base , silhouetting the right heart border and defining the minor fissure , is thought to represent a combination of atelectasis , pleural effusion and possibly consolidation . Opacification at the left lung base is presumably atelectasis . These findings limit limite evaluation of heart size . There is no evidence for pulmonary edema . No pneumothorax . Mediastinal structures are unremarkable .
    OUTPUT:
    
1 . Opacity at the right lung base is though to represent a combination of atelectasis , pleural effusion and possibly consolidation / infection . Follow up radiographs are needed to document resolution . 2 . Opacification of the left lung base is presumably atelectasis . 3 . No pulmonary edema .
