Where is the station 7 lymph node?
Station 7: Subcarinal Lymph Nodes. —The upper border of station 7 is the carina of the trachea. The lower border of station 7 is the upper border of the lower lobe bronchus on the left and the lower border of the bronchus intermedius on the right.
What is a station 7 lymph node?
Station 7: subcarinal lymph node. Lower zone (inferior mediastinal nodes) Station 8: paraesophageal lymph node. Station 9: pulmonary ligament lymph node. Hilar and Interlobar zone (pulmonary nodes)
Where are the thoracic lymph nodes located?
The nodes are typically seen anterolateral to the trachea with the ligamentum arteriosum located laterally. The subaortic nodes are found in station 5. They are found lateral to the ligamentum arteriosum or left pulmonary artery and near the proximal end of the first part of the left pulmonary artery.
What is Station 4R lymph node?
4R.Lower Paratracheal. From the intersection of the caudal margin of innominate (left brachiocephalic) vein with the trachea to the lower border of the azygos vein. 4R nodes extend from the right to the left lateral border of the trachea.
Are there thoracic nodes?
Thoracic lymph nodes are divided into 14 stations as defined by the International Association for the Study of Lung Cancer (IASLC) 1, principally in the context of oncologic staging. For the purpose of prognostication, the stations may be grouped into seven zones.
How many thoracic lymph nodes are there?
Thoracic lymph nodes are divided into 14 stations as defined by the International Association for the Study of Lung Cancer (IASLC) 1, principally in the context of oncologic staging.
How many lymph node stations are there?
As mentioned, based on lung cancer staging guidelines, the intrathoracic lymph nodes are divided into 14 stations, which are grouped into 7 zones.
Where are axillary lymph nodes found?
armpit
The axillary lymph nodes are a collection of grouped lymph nodes found in the axillary region of the upper limb. The axillary region is commonly referred to as the ‘armpit’, although it is a three-dimensional space bound inferiorly by skin and anteriorly by the clavicle.
What are the 5 groups of axillary lymph nodes and where we can locate them?
They are about 1cm in size and are arranged into five groups: subscapular axillary (posterior), apical (medial or subclavicular), pectoral axillary (anterior), brachial (lateral), and central lymph nodes. The subscapular axillary lymph nodes are located on the lower part of the armpit’s posterior (rear) wall.
How many groups of axillary lymph nodes are there?
[2] The axillary lymph nodes arrange into five groups based on their anatomical relations. Collectively, they drain the wall of the thorax, breast, arm, and upper abdominal wall above the umbilicus.
