Escherichia coli associated hematogenous sternoclavicular joint osteomyelitis: A rare condition with a rare causative pathogen.

Escherichia coli is the most common microorganism that causes urinary tract infections (UTIs), including acute prostatitis. However, E. coli osteomyelitis, especially ones that involve the sternoclavicular joint, are rare hematogenous complications. We present a case of an immunocompetent man who presented with symptoms of UTI and right shoulder pain. Urine cultures and blood cultures grew E. coli. There was radiographic evidence of prostatic abscess and a right sternoclavicular joint osteomyelitis. This case is unique given the rare occurrence of non-traumatic clavicular bacterial osteomyelitis and the type of bacteria involved. In conclusion, it is important for clinicians to be aware of E. coli sternoclavicular osteomyelitis in adults with preceding bacterial prostatitis.
