title: Adult intestinal intussusception caused by an inflammatory myofibroblastic tumor.
abstract: Inflammatory myofibroblastic tumor (IMT), which usually affects young adults and children, is a solid neoplastic mesenchymal proliferation composed of myofibroblastic spindle cells admixed with inflammatory infiltrates. Numerous extrapulmonary sites of these tumors have been found, but intestinal IMT is rare, especially in elderly patient. Its diagnosis is recognized as difficult because the patients usually do not have a specific symptom. Here, we present the case of a 79-year-old man with an IMT that caused small intestinal intussusception, which was diagnosed by abdominal ultrasonography. We review the literature on IMT and specially focus on the diagnostic modalities for this disease.
