title: Disseminated pyomyositis mimicking idiopathic inflammatory myopathy.
abstract: Although pyomyositis is uncommon in North America, it may be difficult to distinguish clinically from inflammatory myositis. We describe 2 cases of infectious myositis that were initially diagnosed as inflammatory myositis. As illustrated by these cases, infectious myositis is often a challenging diagnosis and requires a high degree of suspicion.
