Volvulus du grêle sur lipome du mésentère

We report the case of a 7-year old girl presenting with sub-occlusive syndrome associated with acute paroxysmal abdominal pain at the level of the upper abdomen, vomiting and no evacuation of faeces. Physical examination showed discomfort with palpation of the upper abdomen. Abdominal ultrasound showed poorly limited intraperitoneal tissue formation without vascular features on doppler, exercising a mass effect on the neighborhood structures; mesenteric vessels were in their normal position. This mass on CT scan scorresponded to a well limited lipomatous formation exercising a mass effect on the caecum associated with volvulus of the small intestine. The diagnosis of volvulus of the small intestine caused by mesenteric lipoma was retained. Surgical exploration confirmed this diagnosis. The patient underwent unrolling of the small intestine and lipoma enucleation. The postoperative course was uneventful after a follow-up of 6 months. Anatomo-pathological examination confirmed the lipomateuse nature of the mass.
