Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right PICC terminates over the right axilla . There is interval development of a large air loculation in the right lung base with an air - fluid level , significantly progressed from the prior CT of ___ and chest radiograph of ___ . There is surrounding opacification of the right lower lobe , which may reflect compressive atelectasis or superimposed infection . Pleural fluid is also seen tracking along the lateral wall of the right hemithorax . There is mild pulmonary vascular congestion / interstitial edema . The cardiomediastinal contours are incompletely evaluated in the setting of the right basilar collection , but appear grossly stable . A right internal jugular hemodialysis catheter is unchanged in position with the tip likely projecting over the right atrium .
    OUTPUT:
    
1 . Interval development of right posterior basal loculated air-fluid collection , significantly progressed from chest CT of ___ . Surrounding lung opacification may represent compressive atelectasis or superimposed infection . 2 . Pleural fluid extending along the right lateral wall of the hemithorax could represent loculated fluid . 3 . Mild pulmonary vascular congestion / interstitial edema . 4 . Right PICC with tip projecting over the axilla . Recommend repositioning .
