Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A 12 mm right apical pneumothorax is minimally changed compared to the prior study in ___ where it measured 11 mm . No pneumothorax on the left . Lung volumes are lower . New hazy perihilar opacities , right greater than left , is most consistent with asymmetrical pulmonary edema . Minimal atelectasis is likely also present at the left lung base . No other focal pulmonary consolidation . Trace fissural fluid is seen on the right . No pleural effusion on the left . Mild enlargement of the cardiac contour is new . Mildly displaced right - sided lower rib fractures are unchanged . Subcutaneous emphysema along the right lateral chest wall and left tissues of the neck are new .
    OUTPUT:
    
1 . Stable right apical pneumothorax . 2 . New neck and lateral chest wall subcutaneous emphysema , raises the possibility of underlying communication with the pleural space . 3 . Findings consistent with volume overload or heart failure including new cardiomegaly , pleural effusion , and asymmetrical pulmonary edema . 4 . Known mildly displaced right - sided rib fractures .
