What is mesenteric adenitis?
Mesenteric adenitis is inflammation of lymph nodes in the tissue that surrounds your intestines. Lymph nodes are organs of the immune system that help absorb bacteria and toxins from your body. It is caused by infection from bacteria, viruses, or parasites. Mesenteric adenitis may cause dehydration and loss of electrolytes (minerals), such as sodium. Rarely, it could lead to sepsis (a serious blood infection) or an abscess (pus-filled wound) on your intestine.

- You are older than 64 years, or younger than 15 years.
- You are exposed to bacteria, viruses, or parasites that cause infection.
- You drink contaminated water.
- You eat contaminated food, or undercooked meats, especially pork.
- You drink milk that was not pasteurized.

How is mesenteric adenitis diagnosed?
Your blood or bowel movements will be tested for bacteria, viruses, or parasites that caused your condition. You may also need the following:
- An ultrasound uses sound waves to create a picture of your intestines. An ultrasound may be done to show any swelling in your intestines.
- A CT scan, or CAT scan, is a type of x-ray that takes pictures of your intestines. The pictures may show any swelling in your intestines. You may be given dye to help healthcare providers see the pictures better. Tell the healthcare provider if you have ever had an allergic reaction to contrast dye.
How is mesenteric adenitis treated?
Mesenteric adenitis usually goes away without treatment. You may need antibiotics to treat your infection if your condition is severe.
