Pyomyositis is an acute bacterial infection of the muscles characterized by subacute abscess formation. While pyomyositis is rare in temperate climates, the incidence has been increasing, with the majority having comorbidities causing an immunocompromised state, such as HIV and diabetes . Sickle-cell disease has also been implicated as a risk factor for developing pyomyositis [2–4].
Staphylococcus aureus has been implicated in the majority of cases , and recently, ca-MRSA has been found to be an important causative agent in pyomyositis [5, 6]. Because of the rarity of pyomyositis in temperate climates, the diagnosis can be difficult to make, and the patient’s symptoms and exam can easily be mistaken for other diagnoses, such as cellulites . Physicians should consider pyomyositis in patients with severe muscle tenderness in areas of apparent cellulitis and recognize ca-MRSA as an emerging cause of this potentially devastating disease.
