The debate persists about the inflammatory or tumoral, benign or malignant nature of the Inflammatory myofibroblastic tumors (TMI). Radioclinically, they can mimic a malignant neoplasm, although they are classified as intermediate by the World Health Organization (WHO). The diagnosis is almost always made by pathological examination. The treatment is poorly codified but the management is usually surgical. The removal of these tumors is a challenge when the mass is developed at the expense of or in the vicinity of noble organs. Several therapies have been tested to overcome the limitations of surgery, the results are variable. These tumors rarely affect the digestive tract. We propose the study of a case of myofibroblastic tumor developed at the expense of the omentum, five months after a cesarean section, in order to try to determine if it is a rare complication of the postpartum or a fortuitous combination.
