Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison with chest radiographs from ___ , there has been interval removal of a right pigtail catheter . Small bilateral pleural effusions are mildly improved , with a possible loculated appearance of the right effusion . Bilateral lower lobe opacities are unchanged and likely reflect associated atelectasis , less likely pneumonia . Persistent small right apical pneumothorax . There is no new focal consolidation . Mild central vascular congestion with increased interstitial markings could reflect mild interstitial pulmonary edema . Mediastinal and hilar contours are stable . Mild tortuosity and unfolding of the thoracic aorta , as before . Heart size is normal .
    OUTPUT:
    
1 . Status post removal of right pigtail catheter improved small bilateral pleural effusions , with possible loculation on the right . Persistent small right apical pneumothorax . 2 . Persistent bilateral lower lobe opacities suggest atelectasis , less likely pneumonia . 3 . Mild central vascular congestion with increased interstitial markings could reflect mild interstitial pulmonary edema .
