Bacille Calmette-Guérin Vaccine-Induced Tuberculous Elbow Osteomyelitis in an Infant: A Case Report

Case We report a case of Bacillus Calmette-Guérin (BCG) vaccine-induced osteomyelitis of the distal end of the right humerus in a 1-year and 8-month-old girl. The patient was treated with debridement and a 12-month antituberculosis drug. After 3 years of follow-up, no growth disturbances or sequelae were observed. Conclusion BCG osteomyelitis is difficult to diagnose because of its rarity. It is important to suspect BCG osteomyelitis based on symptoms and blood tests and to perform PCR testing. Long-term follow-up after treatment is necessary to monitor for recurrence and avoid growth disturbances until epiphyseal line closure occurs.
