In a 2019 study, of the 1,075 people who underwent an endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to diagnose swollen chest lymph nodes, cancer was the most common reason for the swollen chest lymph nodes, with 61.6% having some form of this disease.
Other causes: Other serious health issues, such as heart failure or interstitial lung disease, can sometimes cause swollen chest lymph nodes. However, mononucleosis, a viral infection, rarely causes the lymph nodes in the chest to swell. Examples include bacterial, viral, fungal, and parasitic infections, such as pneumonia, HIV, histoplasmosis, and toxoplasmosis, respectively. Other infections: Other infections, especially those that affect the lungs, may cause swollen lymph nodes. Tuberculosis: Tuberculosis is a serious infection that affects the lungs and may spread elsewhere in the body. A 2019 study found that it was one of the most common noncancerous reasons for swollen lymph nodes in the chest. Sarcoidosis: Sarcoidosis is an inflammatory disease that can damage the lungs. It can affect lymph nodes anywhere in the body and may begin in the chest or spread to the chest from other lymph nodes. Lymphoma: Lymphoma is a cancer of the lymph nodes. Lung cancer: Swelling in the lymph nodes surrounding the lungs and in the chest may mean that a person has lung cancer or that lung cancer is spreading to other areas of the body. Swollen lymph nodes in the chest often mean a person has a serious underlying medical condition. The site of the swelling often provides clues to the source of the problem.įor example, a person with a swollen lymph node in the neck might have a tooth abscess or strep throat. Swollen lymph nodes may occur in a single location or throughout the body. They can also swell for no apparent reason, either because of chronic health issues or due to lymph node diseases, such as Kikuchi disease. These small nodes sometimes swell when the body is filtering out something harmful. It includes a network of vessels, similar to blood vessels, connecting the many different lymph nodes. The lymphatic system is part of the immune system, and it helps filter out harmful materials, such as infections or cancer cells. Where are lymph nodes located skin#
The chest wall thoracic lymph nodes receive drainage from the breasts, arms, pectoral muscles, and other muscles and skin located in the upper section of the chest.Share on Pinterest Lucas Ottone/Getty Images The posterior mediastinal group of lymph nodes, located near the thoracic aorta, is closely linked to the tracheobronchial group and primarily drains into the thoracic duct. These accept drainage from the heart, lungs, bronchi, and thoracic trachea as well as other lymph nodes. The paratracheal and tracheobronchial groups of lymph nodes are located in the neck and also in the junction where the trachea meets the bronchi, respectively.
The lung lymph nodes can be found along the bronchi. For diagnostic purposes, lymph nodes of the thorax can be further divided into sub-categories. However, any changes in the size or amount of these lymph nodes could be indicative of several types of extrapulmonary or pulmonary diseases. Due to their location, abnormalities of the lymph nodes in the thorax, or chest, are not easily detected. Thoracic lymph nodes are separated into two types: parietal lymph nodes located in the thoracic wall, and visceral lymph nodes, which are associated with the internal organs.
