Where are the intestinal lymph nodes located?
They are also present throughout the abdomen adjacent to all the internal organs, in the mesentery of the intestines that carries the blood vessels to and from the intestines as well as in the retroperitoneal area next to the major blood vessels like the aorta or the inferior vena cava.
What are the lymph nodes in the abdomen called?

Are lymph nodes in abdomen normal?
Reports of the upper limits of normal for lymph node size at abdominal computed tomography have varied from 6 to 20 mm. Establishment of an upper limit for node size by specific location, analogous to that which has been reported for mediastinal lymph nodes, was sought.
What is the intestinal node?
The lymph nodes that become inflamed are in a membrane that attaches the intestine to the lower right region of the abdominal wall. These lymph nodes are among the hundreds that help your body fight disease. They trap and destroy microscopic “invaders” like viruses or bacteria.

What causes lymphadenitis in the back of the intestine?
The most common cause of mesenteric lymphadenitis is a viral infection, such as gastroenteritis — often called stomach flu. This infection causes inflammation in the lymph nodes in the thin tissue that attaches your intestine to the back of your abdominal wall (mesentery).
What does it mean when you have mesenteric lymphadenitis?
When the condition affects the lymph nodes in the membrane that connects your bowel to the abdominal wall (mesentery), it’s called mesenteric lymphadenitis (mez-un-TER-ik lim-fad-uh-NIE-tis). Mesenteric lymphadenitis, which is also called mesenteric adenitis, usually results from an intestinal infection.
