Where do mediastinal lymph nodes drain?

The right group of nodes, which are juxtaposed to the pericardium and the distal part of the intrathoracic inferior vena cava, drain the central diaphragm and the convex surface of the liver. They subsequently drain to the parasternal, posterior mediastinal and brachiocephalic lymph nodes.

How many lymph node stations are there?

14 stations
As mentioned, based on lung cancer staging guidelines, the intrathoracic lymph nodes are divided into 14 stations, which are grouped into 7 zones.

What is a 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.

Are mediastinal lymph nodes normal?

Findings for 56 patients show the largest normal mediastinal nodes to be in the subcarinal and right tracheobronchial regions. From the distributions of node sizes, thresholds were set above which nodes in any region might be considered enlarged.

Are mediastinal lymph nodes always cancerous?

These mediastinal tumors often begin in the nerves and are typically not cancerous. In adults, most mediastinal tumors occur in the anterior (front) mediastinum and are generally malignant (cancerous) lymphomas or thymomas.

Are small mediastinal lymph nodes normal?

From the distributions of node sizes, thresholds were set above which nodes in any region might be considered enlarged. These thresholds, in agreement with a prior investigation of patients with lung cancer, suggest 1.0 cm as the upper limit of normal for the short axis of a mediastinal node in the transverse plane.

Where is 11R lymph node?

—Interlobar lymph nodes are those that are between the origin of the lobar bronchi, with station 11R on the right and station 11L on the left. Station 11R is subdivided into stations 11Rs, which refers to lymph nodes between the right upper lobe bronchus and the bronchus intermedius, and 11Ri,…

Mediastinal Lymphadenopathy in Lymphoma. Lymphoma, a cancer of a type of white blood cells called lymphocytes, can be categorized as either Hodgkin lymphoma or non-Hodgkin lymphoma. Mediastinal lymphadenopathy is one of the ways to differentiate two diseases.

Where are paratracheal lymph nodes?
