Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a linear opacity in the right mid lung zone , which is likely due to scarring from the prior lung abscess . There is an ill - defined patchy consolidation at the right medial base . The lungs are otherwise clear . There is no pulmonary edema or pleural effusion . There is no pneumothorax . The cardiomediastinal silhouette is normal . There are multiple prominent air - filled loops of presumably large bowel in the left upper quadrant . There is no free intraperitoneal air .
    OUTPUT:
    
1 . Patchy vague opacity at the right base is likely atelectasis in the setting of low lung volumes . In the proper clinical setting , pneumonia can not be completely excluded , however . 2 . Stable right upper lobe scarring from the prior abscess . 3 . Prominent air - filled loops of bowel in the left upper quadrant . Consider dedicated imaging with upright and supine views of the abdomen .
