The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic lymph nodes are different from the paraaortic lymph nodes. The periaortic group is the general group ...
The inferior mesenteric lymph nodes have a subgroup of pararectal lymph nodes. The preaortic lymph nodes receive a few vessels from the lateral aortic lymph nodes, but their principal afferents are derived from the organs supplied by the three arteries with which they are associated–the celiac, superior and inferior mesenteric arteries. Some ...
Usually this is localized (for example, an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell). However, when two or more lymph node groups are involved, it is called generalized lymphadenopathy. Usually this is in response to significant systemic disease and will subside once the person has recovered.
Size, where lymphadenopathy in adults is often defined as a short axis of one or more lymph nodes is greater than 10mm. [29] By extent: Localized lymphadenopathy: due to localized spot of infection; e.g., an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell up

Lymph node enlargement can occur for many reasons. First of all, the lymph nodes function to act as a filter for the reticuloendothelial system. They contain multi-layered sinus by exposing B and T cell lymphocytes and macrophages and are found within the blood. When the immune system recognizes foreign proteins in order to mount an attack, it ...
Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. [1] [2] The enlarged lymph nodes are usually painless. [1] The sweats are most common at night. [1] [2] Many subtypes of lymphomas are known. [8]
The retroaortic lymph nodes (or postaortic lymph nodes) are placed below the cisterna chyli, on the bodies of the third and fourth lumbar vertebrae. They receive lymphatic trunks from the lateral and preaortic glands , while their efferents end in the cisterna chyli .
