[Cystic lymphangioma of the mesentery. A case of intestinal obstruction and a brief review of the literature].

Mesenteric cystic lymphangioma is a rare pathology which is not often described in the literature. Moreover, its etiopathogenesis is still uncertain. It may remain asymptomatic or it may present aspecific painful abdominal symptoms of the sub-acute type correlated with compressive phenomena or, more rarely, with acute intestinal obstruction. Surgery is the only form of treatment for both acute and sub-acute abdominal forms. The authors report a case of two mesenteric cystic lymphangiomas of the ileum which led to the onset of intestinal obstruction caused by ileal volvulus in a 45-year-old man.
