Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior chest radiograph performed earlier on the same date , there has been interval placement of a right - sided pigtail catheter . Right - sided pleural effusion has essentially resolved . Small left pleural effusion persists . There is a small right apical pneumothorax measuring approximately 15 mm from the chest cage . There is mild right basilar atelectasis . Heart is normal in size . Right - sided PICC terminates in the mid SVC . Multiple radiodensities projecting over the right upper quadrant are consistent with prior embolization of multiple portal venous branches . Lucency projecting superior to the pigtail catheter at may represent expected subcutaneous emphysema or air captured in between skin folds .
    OUTPUT:
    
1 . Small 15 mm right apical pneumothorax , without evidence of tension . 2 . Interval placement of a right - sided pigtail catheter , with resolution of the large right pleural effusion . Mild right basilar atelectasis . 3 . Small left pleural effusion .
