An uncommon spontaneous and nontropical pyomyositis

We describe a case of pyomyositis of the thigh caused by Staphylococcus epidermidis in an immunocompetent patient. The outcome was favorable after initiation of treatment combining surgical debridement of muscle abscesses and appropriate antibiotic therapy for a 4-week period. Our case report underlines that magnetic resonance imaging (MRI) may be a helpful method in the management of pyomyositis, in accurately revealing the detailed anatomic extent of the abscessed pyomyositis, and in guiding the surgical debridement of the damaged muscle. Finally, MRI should be performed if there is a strong suspicion of pyomyositis in patients whose ultrasonographic examination is not conclusive.
