Emphysematous osteomyelitis: a case report and review of the literature

Abstract

We report the case of a 15-year-old girl with pelvic and sacral emphysematous osteomyelitis caused by Fusobacterium necrophorum. This infection was cured following four surgical procedures and 4 weeks of intravenous then 4 weeks of oral antibiotics. We review our case alongside the 24 previously reported cases of emphysematous osteomyelitis in the literature. The 25 cases include 15 monomicrobial and 10 polymicrobial infections. The causative organism(s) in all but three cases included an anaerobe or a member of the Enterobacteriaceae family. A significant underlying comorbidity was reported in 18 cases. At least 15 cases required one or more surgical procedures. There was a significant associated mortality with eight (32%) patients dying in hospital at 7 to 56 days after the diagnosis of emphysematous osteomyelitis.
