Abstract

We report the observation of a 5-year-old boy who consults for acute paroxysmal abdominal pain located in the right iliac fossa without other associated signs. The physical examination was completely normal.
Abdominal ultrasound showed a multi-compartmentalized cystic mass, without vascular character on Doppler, without mass effect on neighboring structures; the mesenteric vessels were in the normal position.
On computed tomography this mass corresponded to a mesenteric formation attached to the cecum containing several septas. The diagnosis of cystic lymphangioma or mesenteric lipoma was made. Surgical exploration confirmed the diagnosis of mesenteric lipoma attached to the ileum. Resection with anastomosis was performed. The post-operative consequences were simple. Pathological examination confirmed the lipomatous nature of the mass. At the end of this observation, we highlight this rare pathology with possible complications.
