Disease: Mesenteric lymphadenitis

Overview

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.

Symptoms

Signs and symptoms of mesenteric lymphadenitis may include:

  • Abdominal pain, often centered on the lower, right side, but the pain can sometimes be more widespread
  • General abdominal tenderness
  • Fever

Depending on what's causing the ailment, other signs and symptoms may include:

  • Diarrhea
  • Nausea and vomiting
  • General feeling of being unwell (malaise)

When to see a doctor

Abdominal pain is common in children and teens, and it can be hard to know when it's a problem that needs medical attention.

In general, call your doctor right away if your child has episodes of:

  • Sudden, severe abdominal pain
  • Abdominal pain with fever
  • Abdominal pain with diarrhea or vomiting

In addition, call your doctor if your child has episodes of the following signs and symptoms that don't get better over a short time:

  • Abdominal pain with a change in bowel habits
  • Abdominal pain with loss of appetite (anorexia)
  • Abdominal pain that interferes with sleep

Causes

The most common cause of swollen mesenteric lymphadenitis is a viral infection, such as gastroenteritis — often called stomach flu. This infection causes the lymph nodes in the mesentery — the thin tissue that attaches your intestine to the back of your abdominal wall — to become inflamed.

Your lymph nodes play a vital role in your body's ability to fight off illness. They're scattered throughout your body to trap and destroy viruses, bacteria and other harmful organisms. In the process, the nodes closest to the infection can become sore and swollen — for instance, the lymph nodes in your neck may swell when you have a sore throat. Other nodes that commonly swell are located under your chin and in your armpits and groin.

Some children develop an upper respiratory infection before or during a bout of mesenteric lymphadenitis. Experts think there may be a link between the two.

Diagnosis

To diagnosis your child's condition, your doctor is likely to:

  • Perform an exam and take your child's medical history. Your doctor will give your child a physical exam and gather details about his or her signs and symptoms. Your doctor likely will ask about any other medical conditions for which your child has been treated.
  • Request laboratory tests. Certain blood tests can help determine whether your child has an infection and what type of infection it is.
  • Order imaging studies. A computerized tomography (CT) scan of your child's abdomen can help differentiate between appendicitis and mesenteric lymphadenitis. Abdominal ultrasound also may be used.

Complications

If swollen lymph nodes are caused by a serious bacterial infection that isn't treated, the bacteria could spread to your bloodstream, causing a potentially life-threatening infection (sepsis).

Lifestyle and home remedies

For the pain and fever of mesenteric lymphadenitis, have your child:

  • Get plenty of rest. Adequate rest can help your child recover.
  • Drink fluids. Liquids help prevent dehydration from fever, vomiting and diarrhea.
  • Apply moist heat. A warm moist washcloth applied to the abdomen can help ease discomfort.
