Commonly affects the ileocecal region (90% in the terminal ileum) and mimics Crohn disease.
Barium follow-through
• Deep fissures and large, shallow, linear ulcers with elevated margins are characteristic.
• Hourglass stricture of the caecum.
• Incompetent, thickened, rigid and gaping ileocecal valve.
• Nodular fold thickening leads to fold effacement and distortion in later stages—crosses into the cecal pole, which may show more obvious ulceration prior to fibrosis and the ‘shrinking caecum’.
CT
• Low-attenuation lymph node enlargement
• TB peritonitis = diffuse mesenteric/omental nodules, dense ascites and peritoneal thickening
