In contrast to the functional subdivisions, intrathoracic LN locations have been traditionally mapped into 14 stations according to their relationship to landmarks encountered during mediastinoscopy and thoracotomy for lung cancer. Dividing the mediastinum helps to narrow down the lengthy differential diagnoses, which can present in the thorax (including, but not limited to: infections like tuberculosis, the nodal spread of lung cancer, sarcoidosis, lymphoma, silicosis, and asbestosis). Lymph nodes (LNs) are present in all three functional compartments of the mediastinum, though most lymphatic tissue is found in the anterior and middle compartments, and the etiology of lymphatic pathology varies by subdivision. These subdivisions are used to describe the locations of lesions, thereby helping to facilitate differential diagnoses and communication between providers. The mediastinum is classically subdivided into three functional divisions: anterior (pre-vascular), middle (visceral), and posterior (paravertebral) mediastinum. A blood test and possibly biopsy of the lymph node itself will often reveal any abnormalities.The mediastinal compartment contains multiple critical organs and vessels and serves as the central hub for lymphatic drainage. Upon physical examination, the doctor will touch them to get a better idea of how inflamed they actually are. Your doctor will generally get a full history of symptoms to get a better idea of why you may have swollen lymph nodes. However, if they remain for an extended duration and are accompanied by another symptom such as fatigue and weight loss, there may be a serious underlying condition you should have assessed right away. Typically, swollen lymph nodes go away after the underlying infection has been treated successfully. Having swollen lymph nodes may not always be cause for concern, but in some cases it’s worth having a medical professional look at them.

Metastasis (when cancer spreads from one part of the body to another) and leukemia (cancer of the blood) may also trigger swollen lymph nodes. Swollen posterior cervical lymph nodes are seldom a feature of cancer, but may be present in lymphoma-a cancer of the lymphatic system. However, it is important to note that this effect is only temporary, and the vaccine is considered safe to use. Live vaccines, such as the MMR vaccine given to children, can be virulent enough to cause posterior cervical lymph nodes to swell. Drugs and vaccinesĬertain drugs, such as carbamazepine and phenytoin, have swollen neck lymph nodes as a side effect. Some other examples are rheumatoid arthritis, HIV/AIDS, and systemic lupus erythematosus (SLE). Autoimmune disease, where your own immune system mistakenly sees your own body as a foreign invader and attacks it, is one trigger behind swollen lymph nodes. They can also cause a multitude of health complications. Some common infections leading to swollen posterior cervical lymph nodes are:ĭiseases that affect the immune system’s ability to do its job can lead to the lymph nodes in the neck becoming swollen. Additional symptoms may include body aches, congestion, and fever. Lymph node inflammation is often tender to the touch and feels raised. The most obvious reason for developing swollen posterior cervical lymph nodes is an infection in or affecting the head region. Other causes of swollen posterior cervical lymph nodes: Infection Once this pathway has been cleared by the body, flow can return to normal and cause the lymph node to return back to normal size. Sometimes lymph node swelling may be due to the blockage of lymphatic vessels from an infection or abnormality. Causes of swollen posterior cervical lymph node This usually causes them to swell in size. Because of this, doctors can use them to pinpoint where an infection may be located.ĭuring times of infection or disease, lymph nodes will begin to release more lymphocytes (white blood cells). The neck region-along with several other different groups of lymph nodes throughout the body, all of which are responsible for their designated region-helps deploy immune cells and drain lymphatic fluid. Lymphatic tissue takes the form of nodes and vessels to form the lymphatic system of the body. Lymph nodes are major sites of B and T lymphocytes and other white blood cells making them vital parts of the immune system. They are linked by the lymphatic vessel as part of the circulatory system. Lymph nodes are oval or kidney-shaped glands that are widely spread out throughout the body.
