Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A single portable frontal radiograph of the chest was acquired . As before , there is a pigtail catheter ending at the left lung base , not significantly changed . A moderate left pleural effusion is not significantly changed . Consolidation at the left lung base is similar in appearance to the prior radiographs from earlier today , likely compressive atelectasis , although infection in this region is not excluded . Increased heterogeneous opacities at the right lung base are thought to be related to bronchovascular crowding in the setting of slightly lower lung volumes on the present study . The heart size is difficult to assess but is not significantly changed . The mediastinal contours are also unchanged . There is no evidence of pneumothorax .
    OUTPUT:
    
1 . No significant interval change in moderate left pleural effusion or consolidation at the left lung base that is thought to represent atelectasis , although infection in this region is not excluded . 2 . No significant interval change in position of left basilar pigtail catheter .
