Emphysematous osteomyelitis of the forefoot.

Emphysematous osteomyelitis is a very rare, potentially fatal infection that requires immediate diagnosis and prompt treatment. Emphysematous osteomyelitis is usually considered whenever intraosseous gas is detected on imaging. Most organisms implicated in emphysematous osteomyelitis are members of the Enterobacteriaceae family or anaerobes; sometimes the infection is polymicrobial. We report a case of emphysematous osteomyelitis of the forefoot in a 33-year-old man with type 1 diabetes mellitus.
