[Lymphangioma of the mesentery. A rare cause of acute abdominal pain syndrome in adults].

We report about one case of cystic lymphangioma of the jejunum in a 27-year-old woman admitted to hospital for abdominal pain. The study of this case and the review of the literature enabled us to bring out the main characteristics of the lesion: rarity in adults, benignancy, mode of occurrence--most often painful--, radiological--and particularly CT--features, diagnosis based on histological findings only, and lastly, treatment with surgical exeresis that must be complete to prevent recurrence.
