Inflammatory myofibroblastic tumor:A rare cause of invagination in adults

Inflammatory myofibroblastic tumor (imt) is a distinct pseudosarcomatous lesion arising in the soft tissues and interior organs of children and young adults. it is rarely seen in adults. it was first described in lungs. imt can occur in any location in the body. however,it is seen most commonly in lungs,intestinal mesentery and liver. non-mesenteric alimentary tract imt’s are quite rare. the presented case is an ileal imt that caused small bowel invagination. a 38 year-old male patient presented to the emergency department with the complaint of diffuse abdominal pain,distension and no passage of gas or stools for two days. an bdominal examination revealed distension and tenderness in the abdomen with no guarding or rebound tenderness. computerized tomography (ct) of the abdomen was ordered. ct revealed an image compatible with invagination of the right lower quadrant of the abdomen and a mass inside the lumen measuring 4×3×3cm. the mass causing invagination was detected during the surgical operation. a segmentary small bowel resection and ileoileal anastomosis was performed. the patient was discharged uneventfully on the postoperative sixth day. the diagnosis of imt was confirmed histologically and immunochemically. © 2016,professional medical publications. all rights reserved.
