Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is leaning to the left . Again seen is the pigtail catheter overlying the right lung base . Minimal blunting of the right costophrenic angle could represent a small right pleural effusion , but is not significantly changed . No large effusion or evidence of pneumothorax is identified . Hazy opacities are again seen in the right perihilar region and left base , non-specific , but compatible with atelectasis . No gross left effusion . Fixation hardware of the thoracic spine and partially imaged hardware of the lower cervical spine again noted . Cardiomediastinal silhouette is probably not significantly changed .
    OUTPUT:
    
Possible minimal fluid at the right costophrenic angle , grossly unchanged . Otherwise , I doubt significant interval change .
