Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior study the has been insertion of pigtail catheter in the left pleural space at the mid aspect . As a consequence there has been interval substantial decrease in the amount of pleural effusion in particular at the basal aspect of the pleura . Currently the effusion continues to be loculated containing multiple foci of air , most likely trapped within the effusion . The prior study there has been interval elevation of the hemidiaphragm , slight potentially due to decrease in the amount of pleural fluid with subsequent slight right mediastinal shift . Left chest wall air is demonstrated along the tract of the catheter . No pneumothorax seen outside of the fluid collection . No appreciable pericardial effusion is seen . Minimal amount of right pleural fluid is demonstrated , increased since the prior study . Imaged portion of the upper abdomen demonstrate large cortical cyst in the left kidney as well as gallbladder sludge and foci of calcification in the right kidney . Airways are patent to the subsegmental level bilaterally except fall left lower lobe and lingula where atelectasis is noted most likely due to combination of effusion and elevated left hemidiaphragm . Except for minimal a right lower lung atelectasis right lung is clear . Off note is soft tissue lesion , 2 .3 x 1 .7 cm , pleural or extrapleural based , series 4 , image 148 , unchanged in appearance since previous CT obtained 2 days ago . No lytic or sclerotic lesions worrisome for infection or neoplasm demonstrated . Erosive changes at the manubrial sternal joint suggesting prior inflammation as previously . Septal thickening in the left upper lobe is minimal . Besides left lower lobe atelectasis no new findings demonstrated .
    OUTPUT:
    
Interval decrease in size in loculated left pleural effusion after placement of the pigtail catheter . Multiple loculated bubbles of air . Subcutaneous air . Left lower lobe consolidation , most likely a combination of atelectasis or infection with no possibility to exclude underlying mass . Unchanged appearance of the right chest wall / pleural lesion . Potentially as previously suggested 8 might be related to previous fracture of the left seventh rib but followup is required to exclude the possibility of neoplastic origin . No changes in the intra-abdominal findings demonstrated but there is higher elevation of left hemidiaphragm potentially due to drainage of pleural effusion with more pronounced right mediastinal shift .
