A trace pneumothorax is suspected , however , on the right . There is no evidence for pleural effusion . The lungs appear clear . The cardiac , mediastinal and hilar contours are unremarkable within the limitations of technique . Right second through fourth rib fractures are markedly displaced . There are also non-displaced fractures involving right posterior sixth and seventh ribs although the age of the latter fractures is difficult to assess . Given the limitations of technique , additional injuries are difficult to exclude .
