Mesenteric lymphadenitis is an inflammation of lymph nodes. The lymph nodes that become inflamed are in a membrane that attaches the intestine to 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.

Mesenteric lymphadenitis often causes abdominal pain. It is most common in children and teens.
Mesenteric Lymphadenitis Causes:
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. Although less well known, you also have lymph nodes in the mesentery the thin tissue that attaches your intestine to the back of your abdominal wall. The most common cause of swollen mesenteric nodes is a viral infection, such as gastroenteritis commonly but incorrectly known as stomach flu. Some children develop an upper respiratory infection before or during a bout of mesenteric lymphadenitis, and experts speculate that there may be a link between the two.
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). In some cases, swollen lymph nodes are found on imaging tests for another problem. Mesenteric lymphadenitis that doesn't cause symptoms may need further evaluation.
Diagnosis: This disease can be diagnosed by several tests.
• Take your child's medical history: In addition to gathering details about your child's current 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.
Treatment: Mild, uncomplicated cases of mesenteric lymphadenitis and those caused by a virus usually go away on their own. Medications used to treat mesenteric lymphadenitis may include:
• Over-the-counter (OTC) pain relievers and fever reducers may help relieve discomfort. However, avoid giving aspirin as this increases the risk of Reye's syndrome in children.
• Antibiotics may be prescribed for a moderate to severe bacterial infection. For the pain and fever of mesenteric lymphadenitis, have your child:
• Get plenty of rest. Adequate rest can help your child recover.
Mesenteric lymphadenitis disease statistics in Spain: Mesenteric lymphadenitis can occur in adults but is more common in children and adolescents younger than 15 years, and this condition during childhood or adolescence is linked to a significantly reduced risk of ulcerative colitis in adulthood. Frisch et al reviewed Swedish and Danish cohort studies involving 709,353 patients who had undergone appendectomy and were followed up for subsequent ulcerative colitis to determine the role of appendicitis and mesenteric lymphadenitis in the risk of ulcerative colitis following appendectomy. The investigators also studied the impact of appendectomy in 224,483 patients with a family history (parents or siblings) of inflammatory bowel disease and found that regardless of familial predisposition to inflammatory bowel disease, appendicitis and mesenteric lymphadenitis during childhood or adolescence is linked to a significantly reduced risk of ulcerative colitis in adulthood. Mesenteric lymphadenitis generally is a benign disease, but patients with sepsis may have a fatal outcome. The condition affects males and females equally. Yersinia infection is more common in boys than in girls.A 41 year old female with history of asthma and menorrhagia and an associated iron deficiency anemia was hospitalized for syncope. She had been experiencing fatigue, anorexia and excessive thirst for ten days and low grade fevers for one day. History was negative for recent travel, sick contacts, tuberculosis exposure, and smoking, drinking alcohol or illicit drug use. The syncope was attributed to anaemia. Examination revealed tender left posterior cervical adenitis, confirmed by CT scan. Extensive work-up including blood cultures, urine cultures, and HIV were all negative. She was empirically started on ampicillin-sulbactam and responded well in terms of decrease in size of neck swelling but fever persisted. She was discharged home on amoxicillin-clavulanate, but she was non adherent with the same.
