Inflammatory Myofibroblastic Tumor of the Ileum Causing an Unusual Ileocecal Intussusception

Inflammatory myofibroblastic tumor (IMT), also known as inflammatory fibrous polyps or inflammatory pseudotumor, is a rare mass-forming lesion characterized by fibroblastic or myofibroblastic spindle cell proliferation with varying degrees of inflammatory cell infiltration. IMTs usually present in children and young adults. IMTs occur only rarely in the gastrointestinal tract, and these usually occur in the stomach as well as in the small and large bowel. When localized in the small bowel, the presenting symptoms are colic abdominal pain and obstruction. Intussusception due to IMT is uncommon. We report one case of an IMT of the terminal ileum in a 50-year-old female with presentation of ileocecal intussusception and intestinal obstruction.
