Tuberculosis of the colon is re-emerging, particularly in high-risk individuals. Suspect intestinal tuberculosis in patients with chronic abdominal pain and weight loss, especially those with risk factors.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Gastroenterology

Background:

  • Tuberculosis (TB) incidence declined with chemotherapy but is rising in specific populations.
  • Colon tuberculosis (CTB) has increased since the 1980s, linked to HIV, renal disease, and immunosuppression.
  • Risk factors for CTB include HIV infection, chronic renal disease, and prolonged steroid therapy.

Observation:

  • Two patients presented with chronic abdominal pain, weight loss, and a right lower quadrant mass.
  • Imaging revealed retroperitoneal lymphadenopathy and thickened colonic walls.
  • Colonoscopy showed ulcerative lesions and ileocecal valve disruption.

Findings:

  • Microscopic examination confirmed Mycobacterium tuberculosis in intestinal contents.

  • Diagnostic findings included miliary reticulonodular patterns on chest radiography.
  • Abdominal CT scans indicated retroperitoneal lymphadenopathy and colonic wall thickening.

    • Implications:

    • Colon tuberculosis should be considered in patients with unexplained chronic abdominal pain and weight loss.
    • Increased incidence highlights the need for heightened awareness and diagnostic vigilance.
    • Early diagnosis and treatment are crucial for managing this re-emerging infectious disease.
