Mesenteric lymphadenitis

Mesenteric lymphadenitis is a condition characterized by inflammation of the lymph nodes in the mesentery. The mesentery is a fold of tissue in the abdomen that attaches the intestines to the posterior abdominal wall. Mesenteric lymphadenitis is often mistaken for appendicitis due to the similar symptoms.

Causes

Mesenteric lymphadenitis is usually caused by an infection, such as a virus or bacteria. The most common cause is a viral infection, such as gastroenteritis. Other causes can include bacterial infections, parasitic infections, and diseases of the gastrointestinal tract.

Symptoms

The main symptom of mesenteric lymphadenitis is abdominal pain. The pain is usually located in the lower right part of the abdomen, which is similar to the pain experienced in appendicitis. Other symptoms can include fever, nausea, vomiting, and diarrhea.

Diagnosis

The diagnosis of mesenteric lymphadenitis is usually made based on the patient's symptoms and a physical examination. Imaging tests, such as an ultrasound or CT scan, may be used to confirm the diagnosis. In some cases, a biopsy of the lymph nodes may be necessary.

Treatment

Treatment for mesenteric lymphadenitis usually involves managing the symptoms. This can include pain medication, antibiotics if a bacterial infection is suspected, and rest. In severe cases, surgery may be necessary.
