There are several: possibilities. Sometimes excess fat in that region can cause that appearance. Particularly in elderly, tortuosity and prominence of large blood vessels can do it. If there has been trauma, bleeding in the mediastinum can do it. Enlarged lymph nodes and other masses in the area can do it. Or, it can just be normal variation. Your doc might want to get a chest CT to sort it out.
