Intestinal tuberculosis with small bowel stricture and hemorrhage as the predominant manifestation: Three case reports

Figure 1 Small bowel endoscopy and pathology images from case 1. A: A circular ulcer with luminal narrowing and mucosal hyperplasia located in the middle segment of the ileum; B: Another circular ulcer with a narrowing located in the middle segment of the ileum; C: A longitudinal ulcer with mucosal hyperplasia located in the terminal segment of the ileum; D: Histopathological examination by hematoxylin-eosin (200 ×) staining demonstrated the formation of multiple granulomas.

Figure 2 Computed tomography, small bowel endoscopy, and pathology images from case 2. A: Computed tomography scan showing multiple strictures in the small intestine; B: CT scan showing multiple strictures and thickening of the colonic wall; C: CT scan showing multifocal patchy opacities in the upper lungs; D: CT scan showing multifocal patchy opacities in both lungs, predominantly in the right middle lobe and left lower lobe; E: An ulcer with purulent exudate and surrounding mucosal hyperplasia was observed at the terminal ileum; F: An ulcer with luminal involvement was observed at the terminal ileum; G: Histopathological examination via hematoxylin-eosin staining (100 ×) revealed the presence of multiple granulomas; H: Histopathological examination via acid-fast bacilli staining (400 ×) revealed positive bacteria.

Figure 3 Computed tomography, small bowel endoscopy, and pathology images from case 3. A: Computed tomography enterography revealed localized thickening of the small intestine with clustering in the lower left abdomen; B: Small bowel endoscopy revealing ileal stenosis; C: Histopathological examination by hematoxylin-eosin staining (100 ×) demonstrated the formation of granulomas; D: Histopathological examination by hematoxylin-eosin staining (200 ×) demonstrated advanced dysplasia in the gastric mucosa and focal carcinoma in situ.
