Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The right - sided PICC line is visualized with the catheter tip at mid SVC . Lung volumes remain low . There are multiple densities overlying the left lower lobe . These densities are likely representative of the previously visualized spiculated left pulmonary mass , left pleural thickening involving the major fissure , and post-surgical changes at the left lung base . The previously noted retrocardiac opacity remains stable . No distinct consolidation is noted in the right upper lobe . There is no pneumothorax .
    OUTPUT:
    
1 . Stable appearance of densities overlying the left lower lobe likely representative of the previously visualized spiculated left pulmonary mass , left pleural thickening involving the major fissure , and post-surgical changes at the left lung base . 2 . Faint retrocardiac opacity remains stable and may represent atelectasis versus a developing pneumonia in the proper clinical setting .
