Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart is normal size and mediastinal contours are unremarkable . New since ___ is extensive consolidation in the right mid lung , obscuring the right heart border , but affecting more than the right middle lobe . This is either developing pneumonia or traumatic pulmonary hemorrhage , depending upon clinical history . The left lung is generally clear , and there is no appreciable pleural abnormality , either effusion or pneumothorax . Although no acute fracture or other chest wall lesion is seen , conventional chest radiographs are not sufficient for detection or characterization of most such abnormalities . If the demonstration of trauma to the chest wall is clinically warranted , the location of any referrable focal findings should be clearly marked and imaged with either bone detail radiographs or Chest CT scanning . Stomach and splenic flexure are moderately distended .
    OUTPUT:
    
Extensive pneumonia or posttraumatic pulmonary hemorrhage developing in the right lung over the past 15 hr .
