BCG osteitis in a young child (A clinical case)

We report a clinical case of osteitis in a young child as a complication of TB immunization with BCG vaccine (Bacillus Calmette – Guérin or Bacillus Calmette – Guérin). The differential diagnosis was made based on an immunologic blood analysis with the T-SPOT.TB test. The conducted antitubercular chemotherapy in combination with surgical treatment resulted in a positive clinical and radiologic outcome with the restoration and filling of bone tissue defects. The child continues to be registered with a pediatric phthisiatrist in the VA group of dispensary observation. The recommended period of observation is up to 18 years of age. Timely detection of signs of bone and joint system complications in the BCG postvaccine period is essential for establishing an accurate diagnosis and prescribing adequate treatment and rehabilitation measures.
