[Pyomyositis in AIDS. Apropos of a case]

Pyomyositis is a purulent infection of skeletal muscle, a rare entity in temperate climates. The disease has been rarely reported in patients with AIDS. Staphylococcus aureus is the predominant organism. This article presents a case of pyomyositis following insertion of a central venous catheter. Imaging techniques (ultrasonography, computed tomography and magnetic resonance) are useful for diagnosis. The ultrasound-guided aspiration allows isolation of the etiologic agent. The traditional management is medical and surgical.
