FIGURE 1.4.4 Small bowel hamartomas. Transverse 2D (
A) and 3D endoluminal (
B) images from a screening CT
colonography study show an incidentally detected polypoid mass (arrowhead) located in the proximal ileum, which
was confirmed at capsule endoscopy (
C, arrowhead) and proven to be a hamartoma after surgery (
D).
3D endoluminal image from CT colonography (
E) shows another incidentally detected small bowel lesion, which
demonstrated enhancement at dedicated CT enterography (
F, arrowhead) and was also confirmed at preoperative capsule
endoscopy (
G). Contrast-enhanced CT images (
H and
I) from a symptomatic patient show intussusception from an
elongated jejunal soft tissue mass (
I, arrowheads), which proved to be a large hamartoma after surgical resection.
