Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Indwelling support and monitoring devices remain in place , including a left chest tube and left pigtail pleural catheter . There has been apparent slight change in position of the left pigtail pleural catheter including the extrapleural component projecting lateral to the lower left ribs . A moderate left pneumothorax is present with both apical and basilar components . Although the apical component is unchanged , the basilar component appears more prominent than on the prior study . Cardiomediastinal contours are stable in appearance . Multifocal abnormalities throughout the right lung have slightly worsened , and a confluent opacity at the left base is also worse in the interval . These findings likely represent progressive multifocal pneumonia , although co-existing atelectasis is also evident in the right lower lobe . Right - sided loculated pleural fluid and / or thickening appears unchanged . Finally , note is made of a right PICC , terminating within the right subclavian vein just beyond the junction with the right axillary vein .
    OUTPUT:
    
Worsening multifocal pneumonia , with coexistent atelectasis in the right lower lobe . Moderate left pneumothorax , with increased prominence of basilar component .
