Lymphadenitis is a condition in which your lymph nodes become inflamed. 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. It mainly affects children and teens. This painful condition can mimic the warning signs of appendicitis. Unlike appendicitis, mesenteric lymphadenitis is seldom serious and usually clears up on its own.
