What is mesenteric adenitis?

Mesenteric adenitis, sometimes known as mesenteric lymphadenitis, refers to a condition in which the lymph nodes in the mesentery of the abdomen become inflamed. The mesentery is the tissue that connects the intestines to the internal lining of the abdominal wall. Inflammation of the mesenteric lymph nodes results in abdominal pain, tenderness and fever. The most common cause of mesenteric adenitis is a viral infection within the intestines. Mesenteric adenitis most commonly occurs in children and adolescents in the United States.

The signs and symptoms of mesenteric adenitis can last from a few days up to a few weeks. It is common for mesenteric adenitis to be mistaken for appendicitis, as the signs and symptoms are very similar. The disease course varies among individuals. If you have mesenteric adenitis, you might have mild symptoms, while others may have severe abdominal pain and fever. Mesenteric adenitis is usually not a serious condition, and many cases resolve spontaneously.

Some cases of mesenteric adenitis may be a sign of more serious diseases, such as lymphoma or inflammatory bowel disease. The symptoms can mimic those of appendicitis, which if left untreated may lead to serious symptoms. Seek immediate medical care (call 911) for serious symptoms, such as high fever (higher than 101 degrees Fahrenheit), severe abdominal pain, abdominal swelling, distension or bloating, and nausea with or without vomiting.
