However, a person can take over-the-counter pain relievers to alleviate pain they may experience when swallowing. These infections usually resolve on their own. Viral throat infections, such as colds, can present with swollen lymph nodes, a runny nose, and pinkeye. Swollen lymph nodes in the neck may be due to a viral or bacterial throat infection, such as strep throat. Learn more about swollen lymph nodes in the neck here. A doctor will help a person choose the most suitable treatment based on these factors. The type of treatment necessary will depend on a variety of factors, such as the severity of the disease and a person’s underlying conditions and allergies. The condition usually results from an infection elsewhere in the body. If the infection occurs in several node clusters, a doctor will likely diagnose generalized lymphadenitis. This means the condition only affects a few nodes. The most common type of lymphadenitis is localized lymphadenitis. If multiple clusters of nodes become infected, a person may feel pain and swelling in both their neck and groin. When this happens, lymph nodes swell and are painful to the touch. Lymphadenitis occurs when bacteria, viruses, or fungi in the lymph infect lymph nodes. Below, we list some of many conditions that can cause lymph node swelling. superior border: station 7, i.e.Swollen lymph nodes do not always indicate cancer.Lower zone (inferior mediastinal nodes) Station 8 (left/right): para-esophageal nodes (below carina) inferior border - right: lower border of bronchus intermedius.inferior border - left: upper border of the lower lobe bronchus.Subcarinal zone Station 7: subcarinal nodes inferior border: lower border of the aortic arch.superior border: line tangential to the upper border of the aortic arch.anterior and lateral to the ascending aorta and aortic arch.Station 6: para-aortic nodes, ascending aorta or phrenic superior border: inferior border of the aortic arch.these nodes are in the mediastinum (N2) and their surgical management mirrors that of 4R/4L lymph nodes, hence, pre-carinal nodes are best classified as part of the 4R/4L stations 2Īortopulmonary zone Station 5: subaortic nodes (aortopulmonary window).lymph nodes anterior to the tracheal bifurcation are inferior to the above anatomic definitions and are thus technically unclassified by IASLC.inferior border: superior border of the left main pulmonary artery.superior border: superior border of the aortic arch, i.e.inferior border: inferior border of the azygos vein.superior border: intersection of caudal margin of the left brachiocephalic vein with the trachea, i.e.left (4L) and right (4R) are divided along the left lateral border of the trachea, not the midline.Station 4 (left/right): lower paratracheal nodes 3P: retrotracheal - posterior to the trachea.3A: prevascular - anterior to the great vessels ( superior vena cava on the right, left common carotid artery on the left), posterior to the sternum.Station 3A and 3P: pre-vascular and retrotracheal nodes inferior border of 2L: superior border of the aortic arch, i.e.inferior border of 2R: at the intersection of caudal margin of the left brachiocephalic vein with the trachea, i.e.left (2L) and right (2R) are divided along the left lateral border of the trachea, not the midline.superior border: apex of lung / pleural space, thoracic inlet 2.Upper zone (superior mediastinal nodes) Station 2 (left/right): upper paratracheal nodes station 1 nodes are outside the mediastinum and staged as an N3 disease despite this, they can sometimes be treated with radical intent if they are encompassable in a radiotherapy field.left (1L) and right (1R) are divided by the midline of the trachea.inferior border: strictly the IASLC defines this as the clavicles, which leads to ambiguity, particularly as the clavicle is mobile - a more definitive anatomical boundary is the thoracic inlet, i.e.superior border: lower margin of the cricoid cartilage.Supraclavicular zone Station 1 (left/right): low cervical, supraclavicular, and sternal notch nodes Hilar and interlobar zone (pulmonary nodes).Lower zone (inferior mediastinal nodes).Upper zone (superior mediastinal nodes).
