Fig. 13. Hydronephroureterosis in a 24-year-old male patient with Crohn’s disease. (A, B) Postcontrast-enhanced coronal computed tomography images show intra-abdominal abscess (black arrows; A), distal ileal wall thickening with symmetric bowel wall hyperenhancement (black arrows; B), and extended inflammation in the right ureter (white arrowheads; B) abdomen due to Crohn’s disease. This small bowel inflammation caused intra-abdominal abscess and ureteral obstruction in the right middle ureter (white arrowheads) and right hydronephrosis (white arrows).
