Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were performed . A right - sided internal jugular central catheter is present and terminates in the distal SVC . A butterfly shaped opacity projects over the posterior portion of the right ___ rib and has moved more medial compared to prior . While this is likely external to the patient and related to the central line , it s exact location can not be determined . The lung volumes are low which results in vascular crowding . There is no pleural effusion , pneumothorax or focal airspace consolidation . The cardiac and mediastinal contours are normal . The imaged upper abdomen is unremarkable . There is no displaced rib fracture .
    OUTPUT:
    
1 . Satisfactorily positioned right internal jugular central catheter . 2 . No displaced rib fracture . If concern for a fracture persists , a dedicated rib series with markers would be of utility .
