[About a fatal infectious myositis: case report].

Soft tissues' infections involve fascia and musculature which permit to define different anatomic entities as necrotizing fasciitis or myositis. We describe here the case of an infectious myositis whose initial clinical approach did not allow to get the right diagnosis. The tomodensitometry showed typical lesions which induced an accurate management, but could not avoid the death of the patient because of major wounds and a poor general background.
