Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
