Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a small to moderate right pleural effusion with adjacent atelectasis . Vague opacity at the left lung base laterally on the frontal view is compatible with previously seen metastatic lesion . Vague right upper lung opacities with some adjacent linear opacities air seen in the region of previously characterized metastatic foci as well . More dense right perihilar opacity better characterized by prior CT as metastatic disease . There is an additional lesion abutting the descending thoracic aorta in the retrocardiac region , also present on prior CT scan . Cardiomediastinal silhouette is grossly unchanged . Surgical clips project over the left chest wall . Mild height loss of lower thoracic vertebral body is unchanged from prior CT . There is no free intraperitoneal air visualized .
    OUTPUT:
    
Small to moderate right pleural effusion . Additional regions of consolidation in the lungs seen in the region of prior metastatic disease . Difficult to assess for interval change in these lesions given differences in technique .
