Unveiling the Rare: Sternoclavicular Joint Brucellosis Osteomyelitis-A Case Report and Literature Review.

Brucellosis, an endemic zoonotic infection, often presents with musculoskeletal complications, but sternoclavicular joint (SCJ) osteomyelitis is exceptionally rare. We report a case of a 49-year-old male with SCJ osteomyelitis secondary to brucellosis, emphasizing the diagnostic challenges and management. Advanced imaging and serology were pivotal in confirming osteomyelitis, underscoring the need for clinical suspicion in endemic regions. The patient achieved full recovery with a combination of antibiotics. This case highlights the importance of differentiating osteomyelitis from arthritis in atypical presentations.
