    INPUT: Frontal and lateral views of the chest were obtained . The tip of the right - sided central venous catheter is difficult to assess due to multiple overlying structures , but may be within the right atrium . Round sclerotic focus projecting over the anterior lateral right third rib is again seen . Additionally , there is now a 9 mm ovoid density projecting over the region of the posterior right ninth , anterior right fifth rib , which may be osseous , pulmonary , or external to the patient . The left lung is clear . There is no pleural effusion or pneumothorax . The cardiac and mediastinal silhouettes are unremarkable .
    OUTPUT:
    
Two rounded densities projecting over the right chest , one seen previously in the anterior lateral right third rib . An additional one projecting over the anterior right sixth rib , unclear whether external to the patient , osseous , or pulmonary in nature . Suggest repeat with nipple markers for further evaluation .
