Summary
This study reviewed 22 immunocompetent children with Mycobacterium tuberculosis (MTb) infection. Pulmonary and hilar involvement were most common, but radiologists should consider diverse presentations of childhood tuberculosis.
Area of Science:
- Pediatric Infectious Diseases
- Radiology
- Microbiology
Background:
- Tuberculosis (TB) remains a global health concern, affecting children worldwide.
- Understanding the diverse radiological presentations of Mycobacterium tuberculosis (MTb) in immunocompetent children is crucial for timely diagnosis.
Observation:
- A retrospective review identified 22 immunocompetent children with confirmed MTb infection.
- The majority of affected children (14/22) were 5 years old or younger.
- Pulmonary (15 cases) and hilar (8 cases) involvement were the most frequent radiological findings.
Findings:
- Extrathoracic MTb infection was observed in 4 patients.
- Miliary tuberculosis was diagnosed in 3 infants under 9 months of age.
- Radiological findings varied, underscoring the need for a high index of suspicion.
Implications:
- Radiologists must be aware of the broad spectrum of radiological manifestations of childhood TB.
- Early recognition and diagnosis are critical, especially with increasing incidence in children.
- This highlights the importance of considering MTb in pediatric patients presenting with respiratory or systemic symptoms.
