Insights
Tuberculous osteomyelitis in infants is rare and challenging to diagnose. This case highlights a cystic lesion in a young child
Area of Science:
- Pediatric Orthopedics
- Infectious Diseases
- Skeletal Tuberculosis
Background:
- Tuberculous osteomyelitis of long bones is uncommon, particularly in infants.
- Diagnosis can be difficult due to subtle clinical presentations in endemic areas.
Observation:
- A nine-month-old infant presented with a cystic lesion in the distal radial metaphysis.
- The infant was from a tuberculosis-endemic region.
Findings:
- Surgical intervention (biopsy and curettage) followed by synthetic bone substitute implantation was performed.
- Histopathology confirmed tuberculosis with acid-fast bacilli.
- Anti-tubercular drug therapy led to significant clinical and radiological recovery.
Implications:
- Highlights the importance of considering tuberculosis in the differential diagnosis of pediatric bone lesions.
- Emphasizes the need for early diagnosis and appropriate treatment of skeletal tuberculosis in infants.
- Suggests a multidisciplinary approach for managing rare pediatric bone infections.
Abstract:
Tuberculous osteomyelitis affecting long bones is a rare form of tuberculosis. Among infants born in endemic region, often it is difficult to diagnose owing to its subtle clinical features. Here, a case of tuberculous osteomyelitis affecting the distal radial metaphysis is reported, presenting as a cystic lesion in a nine-month-old male infant. Open biopsy with curettage was performed followed by filling of the cavity with synthetic bone substitute (beta tricalcium phosphate granules). The diagnosis was confirmed by histopathological examination and demonstration of acid fast bacilli. Further treatment with anti-tubercular drugs led to clinical and radiological improvement. This case report highlights the importance of keeping tuberculosis as a differential diagnosis while dealing with cases with similar presentation in an endemic region.

Pulmonary Tuberculosis I
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.
