It normally contains a small amount of fat in between but can form a stripe of variable thickness if there is a lot of fat present or by the presence of the thymus in ...

The anterior junction line can be seen on about 40% of up-right chest radiographs (1), although it can be obscured on a portable radiograph. While the coalescence of the pleura can be difficult to visualize on CT images, 3D modeling demon-strates how the pleura drapes over the mediastinum, forming the anterior junction line (Fig 2).
Jul 21, 2019 · Anterior and posterior junction lines. (A) Detail view of a chest radiograph showing the anterior junction line (arrowheads) extending from the level of the aortic arch inferiorly and obliquely to the left and posterior junction line (arrows) above the level of the aortic arch.
