Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present . The carina is poorly delineated , but the tip probably lies approximately 3 .7 cm above the carina . The ET tube tip points toward the right tracheal wall . An NG tube is present and appears to extend beneath the diaphragm and curve , with the tip overlying the gastric fundus . Heart size is borderline versus slightly enlarged . The cardiac silhouette is somewhat globular and a small pericardial effusion would be difficult to exclude . The aortic knob is relatively well - defined . Upper zone redistribution , but no overt CHF . There is a small left apical pneumothorax . No definite pneumomediastinum . Curvilinear density adjacent to the upper heart / left hilum may be related to some overlying material . There is increased retrocardiac density with air bronchograms consistent with left lower lobe collapse and / or consolidation . Hazy density more lateral on left base could represent atelectasis or , less likely , a small amount of layering pleural fluid . There is patchy opacity at the right cardiophrenic region , likely atelectasis . A focus of aspiration is considered less likely . No obvious rib fracture identified on these lung technique films .
    OUTPUT:
    
1 . Suspect mild cardiomegaly . In appropriate the clinical setting , a small amount of pericardial fluid would be difficult to exclude . 2 . Small left apical pneumothorax . No obvious rib fracture identified . 3 . Left lower lobe collapse and / or consolidation , possibly with a small layering left effusion . 4 . Probable right cardiophrenic atelectasis . A focus of aspiration pneumonitis is considered less likely . 5 . Upper zone redistribution , without overt CHF .
