title: [Mesenteric volvulus associated with mesenteric lipoma: about a case].
abstract: We report the case of a 7-year old patient presenting for acute paroxysmal abdominal pain at the level of epigastrium associated with vomiting without involving blockage of materials and gas. Clinical examination and laboratory tests were unremarkable. Abdominal ultrasound was requested as a first line investigationa and showed a right echogenic homogeneous flank and iliac fossa mass with regular contours without vascular Doppler signal and associated with "whirl sign" of mesenteric vessels. On CT scan this mass was seen as a well-defined lipoma formation, exerting a mass effect on the cecum, which was in direct contact with mesenteric volvulus. Arrangement of the mesenteric vessels at their origin was normal. The diagnosis of mesenteric volvulus associated with lipoma was retained. Surgical management and histological analysis of the surgical specimen confirmed the diagnosis. This clinical case aims to highlight the contribution of ultrasound and CT scan in the diagnosis of midgut volvulus.
