Cystic lesions between the mesenteric leaflets, the mesenteric cysts, can be found from the duodenum to the rectum and still have an uncertain etiology. Several hypotheses have already been suggested and the most accepted theory is the formation of cysts due to the rupture of lymphatic vessels. Clinically they do not usually present symptoms and the diagnosis is accidental in about 75% of cases. The incidence is slightly higher in females and the therapeutic approach is mainly surgical, due to the risk of malignancy of the lesion, traumatic rupture, hemorrhage, torsion and compression of adjacent structures. We report the case of a 4-year-old patient with abdominal pain, with a subsequent diagnosis of mesenteric cyst. The postoperative prognosis is good and depends basically on the patient's previous pathologies. The follow-up of relapses, through imaging exams, is still controversial.
