This painful condition, which involves inflamed lymph nodes in the membrane that connects your bowel to your abdominal wall, usually affects children and teens.
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).
A viral intestinal infection is the usual cause of mesenteric lymphadenitis, also known as mesenteric adenitis. It mainly affects children and teens.
This painful condition can mimic appendicitis or a condition in which part of the intestine slides into another part of the intestine (intussusception). Unlike appendicitis or intussusception, mesenteric lymphadenitis is seldom serious and usually clears up on its own.
The mesentery is a fold of membrane that attaches the intestine to the abdominal wall and holds it in place. Mesenteric lymphadenitis is an inflammation of the lymph nodes in the mesentery.

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).
Other causes of mesenteric lymphadenitis include bacterial infection, inflammatory bowel disease and lymphoma.
To diagnosis your child's condition, your doctor will ask your child's medical history and perform an exam. Tests might include:
Mild, uncomplicated cases of mesenteric lymphadenitis and those caused by a virus usually go away on their own, although full recovery can take four weeks or more.
For treatment of fever or pain, consider giving your child infants' or children's over-the-counter fever and pain medications such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) as a safer alternative to aspirin.
Use caution when giving aspirin to children or teenagers. Though aspirin is approved for use in children older than age 3, children and teenagers recovering from chickenpox or flu-like symptoms should never take aspirin. This is because aspirin has been linked to Reye's syndrome, a rare but potentially life-threatening condition, in such children.
Antibiotics might be prescribed for a moderate to severe bacterial infection.
