Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is unchanged deformity of the right hemithorax with volume loss and diffuse calcification , likely related to prior pneumonectomy . Suture chain material projecting over the left mid hemithorax is consistent with prior wedge resections . There is increased opacification at the left lung base silhouetting the left hemidiaphragm and the left heart border with an apparent meniscus compatible with a small left pleural effusion , increased from the prior studies . Patchy airspace opacities in the upper and mid lung zones most likely reflect a combination of pulmonary edema , atelectasis , and pneumonia . There is moderate pulmonary vascular congestion , increased from the most recent prior study . No pneumothorax is detected . The cardiomediastinal contours are difficult to appreciate but overall unchanged .
    OUTPUT:
    
Increased size of small left pleural effusion with pattern in the left lung most compatible with a combination of atelectasis , edema and pneumonia .
