title: Emphysematous Osteomyelitis due to Escherichia coli.
abstract: Emphysematous osteomyelitis, especially that involving the extra-axial skeleton, is an extremely rare presentation but associated with significant morbidity and mortality. Here, we report a case in which a 58-year-old female patient with diabetes mellitus presented with emphysematous osteomyelitis that involved the sternum, clavicle, and pelvic bone and was caused by Escherichia coli via hematogenous spread of urinary tract infection. We successfully treated her with urgent and aggressive surgical drainage with prolonged antibiotics therapy. Early diagnosis and immediate surgical intervention are required for better outcomes in cases of emphysematous osteomyelitis.
