Abstract

Gastrointestinal tuberculosis (TB) accounts for 3.5% of extrapulmonary TB cases and is associated with active or inactive pulmonary TB in 76% of cases. A 53-year-old lady with no prior history of morbidity visited our hospital's department with weakness, an inability to eat, a 39°C fever, no chills, and night sweats that had been present for about six months. Additionally, a colonoscopy revealed a mamelonated mass of a stenotic character in the ascending colon, along with minor mesenteric adenitis, on computed tomography scans of the abdomen and pelvis. The obtained specimen's histological analysis revealed histiocytes and a few large cells producing granulomas without neoplastic features. The colonic biopsy's Löwenstein-Jensen medium culture revealed development of the Mycobacterium TB complex. After receiving therapy for two months with rifampicin, isoniazid, pyrazinamide, and ethambutol, followed by four months with rifampicin and isoniazid, the patient had significantly improved. The current case serves as an example of the difficulty in diagnosing GI TB. The lack of symptoms and occasionally false-positive imaging results reinforce the necessity for increased clinical suspicion.
