Intestinal tuberculosis (TB) is rare in children and difficult to diagnose, especially without lung involvement. Early suspicion and diagnosis are crucial for effective treatment and recovery.
Area of Science:
- Pediatrics
- Infectious Diseases
- Gastroenterology
Background:
- Tuberculosis (TB) presents a significant health challenge in Romania.
- Pulmonary TB is common, but intestinal TB is rare and often a diagnosis of exclusion, particularly in pediatric cases.
- This case highlights the diagnostic difficulties and management of intestinal TB in a child.
Observation:
- A 3-year-old boy presented with severe abdominal pain, melena, malnutrition, and edema.
- Initial investigations revealed anemia, low plasma proteins, inflammatory markers, and abnormal bowel imaging.
- Treatment with parenteral nutrition and antibiotics was ineffective.
Findings:
- The child's mother had a positive QuantiFERON® test and a chest X-ray suggestive of pulmonary TB.
- Bowel biopsy showed granulomas, and staining was positive for Mycobacterium tuberculosis.
- Initiation of specific anti-TB treatment led to significant clinical improvement, including resolution of symptoms and improved growth.
Implications:
- Intestinal TB can mimic other gastrointestinal conditions, posing a diagnostic challenge.
- A high index of suspicion is necessary for diagnosing intestinal TB, especially with atypical abdominal symptoms and no clear pulmonary signs.
- Prompt and accurate diagnosis is essential for effective management and favorable outcomes in pediatric intestinal TB.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
