[Mesenteric lipomas in children: a report on one case (author's transl)].

A case of mesenteric lipoma presenting as an isolated abdominal masse in a boy of 20 months is reported. Diagnosis was made from the appearance of the fatty mass in a straight abdominal film. Radiological examination was completed by urography and echotomography. The analysis of 11 identical cases found in the literature enabled the principal clinical and radiological characterists of this affection to be defined and evoked the problems of differential diagnosis from other lipomatous abdominal masses and cystic lymphangioma.
