A 44-year-old male patient with a known history of familial Mediterranean fever and Crohn’s disease. He had had surgery for small bowel obstruction a few days previously and then complained of abdominal pain and fever. MR enterography (a) axial fat-saturated true-FISP image demonstrates a thickened wall of adjacent small bowel loops (white arrows) with a small amount of free fluid in the peritoneal cavity (open arrow) and some mesenteric fat infiltration. (b) Axial fat-saturated VIBE image after intravenous contrast medium administration demonstrates thickened enhancing wall and particularly serosa (white arrows) of the same small bowel loops. Free air (arrowhead) after the recent operation and a horseshoe kidney are seen
