    INPUT: The cardiac silhouette size appears mildly enlarged . There is widening of the right paratracheal stripe . The aorta is mildly tortuous . Fullness of the left hilum is demonstrated . There is no pulmonary vascular engorgement . The lungs are clear without focal consolidation . No pleural effusion or pneumothorax is demonstrated . A 4 mm nodular opacity in the right upper lobe likely reflects a granuloma . No displaced fractures are identified .
    OUTPUT:
    
1 . No acute cardiopulmonary abnormality . 2 . Widened right paratracheal stripe and fullness of the left hilum could suggest underlying lymphadenopathy . Chest CT should be considered for further assessment . 3 . No displaced rib fractures seen . If there is continued concern for rib fracture , a dedicated rib series can be obtained .
