A 48-year-old male patient with Peutz-Jeghers syndrome complained of abdominal pain. He had undergone Whipple surgery for malignant duodenal tumour previously. MR enterography (a) coronal fat-saturated true-FISP image demonstrates a polyp in the small bowel (white arrow), which caused intussusception (open arrow) of a short segment with bowel-in-bowel appearance. Other polyps (arrowheads) in different parts of the small bowel are seen. The same sequence (b) image demonstrates two pedunculated polyps in the stomach (black arrows). Two months later MR enterography was performed again, (c) coronal fat-saturated VIBE image after intravenous contrast medium demonstrates the same contrast-enhancing pedunculated polyp in the small bowel in the right lower abdomen (white arrow). There are no signs of intussusception; it resolved spontaneously
