Case 3. CT obtained in a 3.5-year-old boy with left duplex kidney & ureters, and congenital megaflop-ureter. Non- enhanced scan obtained at the abdomen & pelvis shows fluid-filled loops, the normal bowel loops are compressed to the right side of the abdominal wall, and a tendon-like shadow can be seen in the bowel loop-like areas (red arrow) (a). The tendon-like shadow was intensified as the normal ureter (red arrow) (b), and the normal bladder was also intensified in the left side pelvis (red arrow) on the 54-min scan (c). Meanwhile, MIP reconstruction shows the position and course of left ureter changed (red arrow) (d). The left ureter shows delayed enhancement on the 3-h and 13-min scan (e). The area of the left side kidney shows a little irregular enhancement on the 23 h and 9-min scan (red arrow) (f). Operation findings (g)
