Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA lateral images of the chest . The lungs are well expanded . Cephalization of the pulmonary vasculature is seen , consistent with pulmonary venous hypertension . The lungs are otherwise clear . There is no pleural effusion or pneumothorax . The cardiomediastinal silhouette is unremarkable . No acute fracture is seen .
    OUTPUT:
    
1 . Cephalization of the pulmonary vasculature consistent with pulmonary venous hypertension . 2 . No acute fracture is seen , however chest radiographs are insensitive for rib fractures . If clinical concern for rib fractures persists , dedicated rib films with markers on any focal point of tenderness would improve detection .
