Mesenteric contusion is a lesion of the mesentery during a severe blunt trauma to the abdomen. The mesentery is a two-layered wall of tissue lining the peritoneum. Mesenteric contusion accounts for 10% of blunt abdominal trauma. We report a case of abdominal trauma received in the radiology department of the Medical Clinic "Les Etoiles" in Mali with the aim of elaborating the limits of computed tomography in the diagnosis of mesenteric contusions. This was a 15-year-old female subject with no particular ATCD received for abdominal trauma following a road accident. Computed tomography found low abundance peritoneal effusion with slight infiltration of mesenteric fat. Faced with deglobulization, the patient was operated on, revealing a mesenteric contusion. The normal abdominal CT in a traumatic context does not always eliminate a mesenteric contusion
