Specifically , there is no evidence of a consolidative process within the lungs . Severe degenerative changes are seen at the left shoulder , and moderate changes on the right , as well as at the acromioclavicular joints . Multiple levels of ossification of the anterior longitudinal ligament are seen , consistent with diffuse idiopathic sclerosing hyperostosis ( DISH ) .
