Abstract

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, is a soft tissue sarcoma arising from mesenchymal tissue of the body. UPS of the gastrointestinal tract is known to be rare and only a few cases have been reported in the literature. Based on our case and review of the other relevant literature, the CT findings of primary UPS of the small bowel included nodular bowel wall thickening with homogeneous enhancement. It presents as a rapidly growing tumor without bowel obstruction, and it may be accompanied by distant metastasis.
