Mesenteric adenitis

Mesenteric adenitis 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 back of the abdominal wall. Mesenteric adenitis is often mistaken for appendicitis due to the similarity in symptoms.

Causes

Mesenteric adenitis is typically caused by an infection. The most common infections that lead to this condition are viral in nature, but bacterial and parasitic infections can also be the cause. The condition is most common in children and adolescents.

Symptoms

The primary symptom of mesenteric adenitis is abdominal pain. This pain is usually centered around the lower right area of the abdomen, which is why the condition is often mistaken for appendicitis. Other symptoms can include fever, nausea, and vomiting.

Diagnosis

Diagnosis of mesenteric adenitis is typically made through a combination of physical examination and medical imaging, such as an ultrasound or CT scan. Blood tests may also be used to help identify the presence of an infection.

Treatment

Treatment for mesenteric adenitis primarily involves managing the symptoms and treating the underlying infection. This can include antibiotic therapy for bacterial infections, and pain management for abdominal pain. In most cases, the condition resolves on its own once the infection has been treated.
