female, 19 year(s)
 
 
  • Figure 1
    Plain abdominal X-ray
     

    The supine (a) and upright (b) positions show gasless right abdomen, distended pelvic ileal loops without significant levels, some gas in the left colon and rectosigmoid.

     
    Area of Interest: Abdomen; Imaging Technique: Plain radiographic studies; Special Focus: Inflammation;

    Axial (a,b) and coronal-reformatted images (c,d) show recurrent ileocecal Crohn disease with convergent loops aspect consistent with enteric fistulisation. Abscess collection abuts the retroperitoneal fascial plane.

    Axial, coronal- and oblique-reformatted images show right hydronephrosis with the dilated lumbar ureter converging towards the abscess abutting the retroperitoneal fascial plane (arrow in d).
