Incidental mass found on screening colonoscopy

Intestinal tuberculosis accounts for 1%-3% of all tuberculosis cases worldwide and typically arises as a secondary manifestation of hematogenous spread rather than as a primary site of infection. The condition is characterized by an insidious onset, with patients often presenting late in the disease course with non-specific gastrointestinal symptoms. At advanced stages, clinical features may include signs of bowel obstruction or perforation, closely mimicking other conditions such as colorectal malignancy, colitis, or inflammatory bowel disease, posing a significant diagnostic challenge. We report a rare case of isolated intestinal tuberculosis presenting as a partial large bowel obstruction. The patient successfully underwent a right hemicolectomy followed by anti-tuberculosis pharmacotherapy, resulting in complete restoration of normal bowel function and eradication of tuberculosis.
