Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low , with bibasilar atelectasis and likely small left pleural effusion . No overt pulmonary edema is identified . There is no pneumothorax . The right PICC terminates in the low SVC , as before , and right humeral head anchor devices . The cardiomediastinal silhouette is unchanged . A geographic opacity in the left midlung is again seen
    OUTPUT:
    
1 . Low lung volumes with bibasilar atelectasis and small left pleural effusion . No overt pulmonary edema . 2 . Left midlung opacity could conceivably be a pleural plaque given geographic appearance , however in the setting of ARDS , parenchymal consolidation due to pneumonia can not be excluded .
