[Cystic lymphangioma of the mesenterial root as a rare cause of acute abdomen].

Mesenteric lymphangioma is a rare, benign cystic tumor of the lymphatic system, which is commonly found in younger children and may in certain cases lead to an acute abdominal manifestation. The treatment of choice is surgical resection without damage to the blood supply of the bowel. The prognosis is generally favourable, but with increasing tumor size radical resection becomes more difficult and local recurrence more probable.
