Precarinal lymph nodes are found within the chest cavity around the lungs. The significance given to the presence of an enlarged lymph node must be tempered by knowledge of the patients clinical situation. The enlargement of the lymph nodes on the mediastinal x-ray looks like a "pathological shadow" and gives an idea of the localization of the lesion, shape, outlines, mobility, relationship with neighboring organs.
