Colonic tuberculosis mimicking Crohn's disease: case report

Published by National Institutes of Health | U.S. Department of Health & Human Services | Catalog Last Checked: July 31, 2026 at 09:45 PM | Dataset Last Updated: September 06, 2025
Background Intestinal tuberculosis is a rare disease in western countries, affecting mainly immigrants and immunocompromised patients. Intestinal tuberculosis is a diagnostic challenge, especially when active pulmonary infection is absent. It may mimic many other abdominal diseases. Case presentation Here, we report a case of isolated colonic tuberculosis where the initial diagnostic workup was suggestive of Crohn's disease. Computed tomography findings however, raised the possibility of colonic tuberculosis and the detection of acid-fast bacilli in biopsy specimens confirmed the diagnosis. Conclusions In conclusion, this case highlights the need for awareness of intestinal tuberculosis in the differential diagnosis of chronic intestinal disease
