case_images: Image studies of the patient with intestinal tuberculosis initially misdiagnosed as Crohn's disease. a-c Images for making the initial diagnosis of Crohn's disease. a Coronal view of abdominal computed tomography showed skip lesions with interrupted dilatation of the small bowel, and one stricture point at the terminal ileum with the dilated proximal intestine (arrow); b Initial barium radiographic study of the intestine showed segmental narrowing of the ileum, which favored post-inflammatory focal stricture (arrow); c Colonoscopic examination showed polypoid lesion at the terminal ileum. d
  D1 Barium radiographic study of our patient after completion of anti-tuberculous treatment showing patent intestinal structure; D2 Barium radiographic study of another 20-year-old male diagnosed with Crohn's disease showing typical ileocecal valve involvement with cobblestone appearance.

case_images: ACT showed skip lesions throughout the small bowel, and suspected healed enteroenteric fistula with multifocal mesenteric adhesion (Figure 1a). Barium radiographic study revealed segmental narrowing of ileum which favored post-inflammatory focal stricture (Figure 1b). Colonoscopic examination showed the presence of polypoid lesions in the terminal ileum (Figure 1c), of which two pieces were biopsied. Follow-up barium radiographic examination of the intestine (Figure 1d, left) showed no definite residual lesion after completion of his 6-month-course of anti-TB treatment.
