Figure 1 Polyp 1 in a 46-year-old female with known peutz-Jeghers syndrome.
A: Macroscopically, the peutz-Jeghers syndrome (PJS) polyp has a coarse lobulated surface; B: The capsule endoscopy image shows that this polyp is pediculate; C: Microscopically, the analysis confirms a benign hamartomatous polyp with a tree-like branching core derived from the muscularis mucosae covered by normal epithelium; D: Fat-suppressed axial T1-weighted-Gadolinium-enhanced VIBE image shows a moderate enhancement of the polyp, with a good characterization of its size and shape (arrow); E: The coronal T2 True Fast Imaging with Steady-state in Precession (FISP) MR image also allows detection of this isolated ileal polyp (arrow).
Figure 2 Polyp 2 in a 26-year-old female with known peutz-Jeghers syndrome.
Axial fat-suppressed T1 weighted-Gadolinium-enhanced axial image shows the enhancement of the rounded PJS polyp (arrow).
Figure 3 Polyp 3 in a 54-year-old male with known peutz-Jeghers syndrome.
A: Axial fat-saturated Vibe gadolinium-enhanced T1-weighted shows a small-bowel slightly enhancing jejunal polyp (arrow); B, C: The corresponding images on a high b (b = 800) value diffusion-weighted MRI shows a high-signal intensity polypoid lesion inside a jejunal small-bowel loop with a low ADC value compared with the surrounding small-bowel lumen (ADC = 1440 mm2/s) (arrow).
Figure 4 Polyp 4.
A: Multidetector computed tomography (MDCT) coronal view reveals a regular small-bowel polyp with homogeneous enhancement (arrow); B: The double balloon endoscopy optimally depicts this large small bowel polyp.
Figure 5 Polyp 5 in a 44-year-old male with a known peutz-Jeghers syndrome.
A: Coronal and B: an axial Multidetector computed tomography (MDCT) enteroclysis images reveals multiple, regular polyps with various sizes and shapes (arrows); C: The endoscopic view shows a pediculate polyp; D: A coronal MIP reformat shows the typical pediculate peutz-Jeghers syndrome (PJS) polyp aspect.
Figure 6 Twenty-four-year-old male referred at the emergency department for abdominal pain.
The axial Multidetector computed tomography (MDCT) scan shows the bowel-in-bowel appearance with mesenteric fat into the intussusception (arrows).
Figure 7 Axial (A) and (B) coronal fat-saturated Vibe gadolinium-enhanced T1-weighted magnetic resonance images illustrate the target-like or sausage shape of the small-bowel intussusception.
Figure 8 Operative view shows a pediculate polyp that was removed (A) (reprinted with permission from ref.
38) after double balloon enteroscopic evaluation (B).
Figure 9 Twenty-eight-year-old male with a known peutz-Jeghers syndrome presenting a single small-bowel polyp.
A: Multidetector row computed tomography-virtual endoscopy (MDCT-VE) acquired after gas filling shows a single polyp in the intestinal lumen (arrow); B: Corresponding image of this polyp after MDCT-VE post-processing (arrow).
