Abstract

Inflammatory myofibroblastic tumor (IMT) of the ileum rarely develops and moreover, intussusception of the tumor is even rarer. We report a case of IMT of the ileum with ileoileal intussusception in which we obtained multi-detector computed tomography images that revealed dilatation of the proximal ileum as well as luminal mass lesion in the distal ileum with intussusceptum.

  Fig. 1 A 55-year-old man with abdominal pain for one week. A, B. Contrast enhanced axial CT scan demonstrates invaginated mesenteric fat and vessels (arrow) as well as bowel wall thickening of the intussusceptum (open arrow). C, D. Axial (C) and coronal (D) reformatted images show a 2.5 cm sized lead mass (arrowheads) with enhancing thin wall in the distal portion of the intussusceptum. The CT attenuation value of the mass is measured about 34 Hounsfield unit (HU) on unenhanced image (not shown) and about 41 HU on enhanced image. E, F. Gross specimen showing intra-luminal pedunculated solid mass measuring 2.5 × 2.0 cm. Cut surface shows myxoid component and there is no evidence of hemorrhage or necrosis. G, H. Microscopic view of the lesion shows that the tumor is composed proliferation of spindle-shaped myofibroblastic cells and infiltration of inflammatory cells embedded in a highly vascularized stroma (H&E staining, × 40). Immunohistochemistry was positive for smooth muscle actin.
