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.
As realized later, the same disorder had previously been described by Allchim and Hebb in 1895 but they had failed to recognize it as a new disease. Based on the presence of unsplit fat in the stools, intestine, and mesenteric glands, a disease of fat metabolism was supposed. “Rod-shaped organisms in silver-stained gland tissue, closely resembling the tubercle bacillus” were observed but not considered the etiology of the disease. However, no other tissue was available for further analysis. The histological criteria for Whipple's disease were summarized by Black-Schaffer in 1949, periodic acid-Schiff reagent (PAS) was used to stain inclusions in macrophages found in the intestines and mesenteric lymph nodes of patients with this disease. With the help of electron microscopy free rod-shaped bodies with an outer membrane were noticed in the lamina propria. The authors considered the possibility of virus-like particles.
