Colonic tuberculosis masquerading as crohn's disease.

Intestinal tuberculosis (TB) is a diagnostic challenge and can closely mimic Crohn's disease (CD) and colon cancer. These disease entities very closely resemble each other in symptomatology, imaging, appearance, and pathology. We present a case of colonic TB where the initial diagnostic workup was suggestive of CD. However, the detection of Mycobacterium tuberculosis in biopsy specimens confirmed the diagnosis.
