Insights
Bacillus Calmette-Guérin (BCG) osteomyelitis is a rare complication in children following immunization. Early diagnosis and a year of antituberculous therapy led to successful treatment in a young boy with knee pain.
Area of Science:
- Pediatrics
- Infectious Diseases
- Orthopedic Surgery
Background:
- Bacillus Calmette-Guérin (BCG) osteomyelitis is a rare but serious complication of BCG immunization.
- It often presents with nonspecific symptoms, leading to diagnostic delays in immunocompetent children.
Observation:
- A 1-year and 10-month-old male infant presented with persistent knee pain and limping for five months.
- Initial surgical debridement was performed due to suspected malignancy.
Findings:
- Culture of surgical specimens confirmed Mycobacterium bovis-BCG strain, diagnosing BCG osteomyelitis of the distal femur.
- The infant was successfully treated with a one-year course of antituberculous therapy.
Implications:
- This case highlights the importance of considering BCG osteomyelitis in the differential diagnosis of pediatric bone infections, even with vague symptoms.
- Prompt diagnosis and appropriate antituberculous treatment are crucial for favorable outcomes in affected children.
Abstract:
Bacillus Calmette-Guérin (BCG) osteomyelitis in immunocompetent children is a rare complication of BCG immunization which presents with nonspecific findings and often leads to delayed diagnosis. We report a 1-year and 10-month-old male infant with complaining of knee pain and limping for 5 months. He received surgical debridement due to suspicion of malignancy but BCG osteomyelitis of the distal femur was diagnosed with the culture of the specimens which revealed to have Mycobacterium bovis-BCG strain. He was successfully treated with antituberculous therapy lasting for 1 year.
