摘要：

Low-grade fibromyxoid sarcoma ( LGFMS) is a rare tumor that commonly arises in the lower extremities but rarely in the mesentery. We report computed tomography ( CT) and magnetic resonance imaging ( MRI) findings of LGFMS of the small bowel mesentery. On CT, the mass was composed of two components. One component, on its right side, appeared to have isointense attenuation relative to muscle, whereas the other component, on its left side, appeared to have low attenuation. On MRI the mass on the right side showed hypointensity similar to muscle on both T1- and T2-weighted images as well as mostly slight enhancement on contrast-enhanced T1- weighted images. On the other hand, the mass on the left side showed relative hypointensity on T1- weighted images and hyperintensity on T2-weighted images as well as intense enhancement on contrast-enhanced T1- weighted images, suggesting that the tumor contained myxoid tissue. The myxoid area of LGFMS may have a tendency to reveal intense enhancement on contrast-enhanced images.
