Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest x-ray from ___ at 11 :39 and targeted review of chest CT from ___ . Again seen are multiple left - sided rib fractures and a pigtail catheter at the left lung base . There is a small left effusion with minimal atelectasis at the left base . There is a small to moderate size pneumothorax seen at the left lung base against the lower left chest wall and , on lateral view , seen anteriorly . Minimal lucency along the left mediastinum could also be due to the pneumothorax . The mediastinum remains midline , unchanged in configuration . On the right , there is a small effusion , with minimal right basilar atelectasis . There is relative lucency along the right chest laterally . Unless there is reason to suspect a right - sided pneumothorax , there is most likely represents artifact due to overlying soft tissue contours . Upper zone redistribution , but no overt CHF . There is background hyperinflation , consistent with COPD . Of note , there is a 4 .1 mm nodule in the right mid / lower zone laterally , which corresponds to the nodule described on the ___ CT scan for which repeat chest CT in ___ months is recommended .
    OUTPUT:
    
Pigtail catheter at left lung base , with small pleural effusion , minimal basilar atelectasis , and small to moderate - size pneumothorax . The effusion appears slightly larger . As the bulk of the pneumothorax is seen only on the lateral view , comparison to the most recent prior study is limited . Left - sided rib fractures again noted . Small right pleural effusion and minimal atelectasis at right base , unchanged . Lucency at right lateral lung base . Unless there is reason to suspect a right - sided pneumothorax , this most likely represents artifact due to overlying soft tissue contours . If there is concern for right - sided pneumothorax , then an additional frontal view obtained at end - expiration of the respiratory cycle could help for further assessment . Pulmonary nodule in the right mid / lower right lung , also seen on the recent CT scan . As suggested on the chest CT report , repeat chest CT in ___ months is recommended . Background COPD .
