Computed tomography three-dimensional reconstruction in the diagnosis of bleeding small intestinal polyps: A case report

Figure 1 Three-dimensional computed tomography reconstruction of the small intestine, showing the middle part of the ileum. A-D: The portal vein branches can be seen entering the intestinal wall and the intestinal wall encircles the portal vein branches and corresponding mesenteric adipose tissues from the side and protrudes into the intestinal cavity with a total length of about 10 cm.

Figure 2 A large protuberant lesion with hyperemia and swelling was observed. A and B: Capsule endoscopy revealed an obvious entanglement of the intestinal wall and a huge hemorrhagic protuberant lesion in the ileum.

Figure 3 Trans-anal single-balloon enteroscopy was used to identify a large, pedicled tumor measuring approximately 2 cm × 2 cm. A-D: Single-balloon enteroscopy revealed large polyps with large coarse pedicles (about 2 cm × 2 cm at the tip) and erosion and swelling at the tip; E-H: Two nylon rings were placed at the root of the polyp and the head of the polyp turned purple-blue.

Figure 4 Histopathological examinations of the polyp, showing tubular adenoma with low-grade intraepithelial neoplasia, high chronic inflammatory cell infiltration, and local granulation tissue hyperplasia. A: Hematozlin and eosin stain, original magnification × 100; B: Hematozlin and eosin stain, original magnification × 200.
