Colonic tuberculosis mimicking Crohn's disease: case report

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
