Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable chest radiograph is limited by obliqued patient position . Within this limitation , the cardiomediastinal contours are unremarkable . Increased density projecting over the right hilus likely reflects a pulmonary vessel , though this could be further evaluated with properly positioned frontal and lateral chest radiographs . Save minimal atelectatic changes in the lung bases , lungs are clear . No pleural effusion or pneumothorax identified .
    OUTPUT:
    
No finding concerning for pneumonia . Increased density projecting over right hilum likely reflects pulmonary vessel exaggerated by oblique patient position . Could be further evaluated with conventional frontal and lateral chest radiographs when clinically stable .
