Ureteral intussusception associated with a fibroepithelial polyp: a case report

      Abstract

      We present a case of a 67-year-old man with intussusception of the right ureter associated with a fibroepithelial polyp. The concentric sign and line sign are characteristic radiological findings in intussusception, and these findings could be seen in the present case. Although this entity is rare, its radiological findings are specific. Multidetector row computed tomography and its multiplanar reconstruction make the diagnosis feasible, although the qualitative diagnosis of the tumor was difficult.
