    INPUT: AP and lateral views of the chest were provided with patient positioned upright . Evaluation is markedly limited due to underpenetrated technique more so on the lateral view . There is consolidation in the left lower lobe , which could represent aspiration or pneumonia . This finding is more conspicuous compared with prior exam . Lung volumes are low . The imaged portion of the right lung appears clear . The heart and mediastinal contour appear grossly stable . No large pneumothorax .
    OUTPUT:
    
Limited exam with low lung volumes . Increased conspicuity of consolidation in the left lower lobe , question pneumonia versus aspiration .
