Primary pyomyositis in a child

SummaryPyomyositis is a term used to denote primary pyogenic infection of the skeletal muscle. Striped muscle tissue is normally resistant to bacterial infection; pyomyositis is very rare. Primary pyomyositis is a purulent infection of striated muscle that is thought to be caused by seeding from a transient bacteremia. Pyomyositis should be considered in the differential diagnosis of septic-appearing children as well as children complaining of joint pain or muscle aches. The diagnosis can be aided by either a computed tomography or magnetic resonance imaging scan. If the patient does not respond quickly to antibiotics and surgical intervention, there is either a recurrence of the previously debrided abscess or an unrecognized secondary abscess. Here, we present a case of primary pyomyositis of the iliacus muscle that might be due to severe pneumonia in a five-year-old child
