The right paratracheal stripe is also important to assess, as it can reflect a process in the posterior mediastinum, in particular the spine or paraspinal soft tissues; normally it should measure 3 mm or less. The left paratracheal stripe is more variable and only seen in 25% of normal patients on posteroanterior views. [7]
The right and left [citation needed] paratracheal lymph nodes (or paratracheal chains [citation needed]) are lymph nodes in the neck [1] situated lateral to the trachea and esophagus alongside the recurrent laryngeal nerve. They drain to the deep cervical lymph nodes. [2]
These lymph nodes form four main groups including paratracheal, tracheobronchial, bronchopulmonary and pulmonary nodes. Paratracheal nodes are located on either side of the trachea. Tracheobronchial nodes can be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two ...
In radiology, Garland's triad (also known as the 1-2-3 sign) is the concurrence of reasonably symmetrical bilateral hilar lymphadenopathy and right paratracheal lymphadenopathy seen on a chest radiograph. [1] These features are suggestive of thoracic sarcoidosis. [2]

Typically, there are two trunks - one on each side of the body. The right bronchomediastinal trunk may connect the right lymphatic duct, and the left trunk to the thoracic duct, [1] although more frequently, they open independently into the junction of the internal jugular vein and subclavian veins on their respective sides.
The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
