Normal mediastinal contours

  • Here are some of the normal mediastinal contours often seen on chest X-rays
  • These contours are created by difference in density of anatomical structures of the mediastinum and adjacent tissues
  • Not all of these contours are present on all normal chest X-rays and their visibility depends on technical factors
  • Abnormality of these contours may help establish the presence and determine the location of pathological processes of the mediastinum or adjacent structures
  • If one of these contours is obscured, then an abnormality is likely to be located next to the structure that the contour represents
