Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are unchanged compared to the prior study . The cardiomediastinal contour is within normal limits . Visualization of the lung bases is suboptimal due to overlapping soft tissue structures , however there appears to be increased opacity with partial silhouetting of the left heart border suspicious for lingular consolidation . A right - sided PICC terminates in the mid SVC .
    OUTPUT:
    
Assessment of lung bases is somewhat limited due to the overlapping soft tissues , nonetheless increased opacity at the left lung base is suspicious for lingular consolidation .
