Abstract
Primary pyomyositis is a suppurative infection of striated muscle, the diagnosis of which is overlooked or delayed due to its rarity and vague clinical presentation. Though rare in the United States and temperate zones, pyomyositis is more frequently reported from tropical countries. The exact pathogenesis of pyomyositis is uncertain in most cases. The disease progresses through three stages with characteristic features and require a high index of suspicion to institute stage-wise treatment. Newer imaging methods, particularly magnetic resonance imaging, have facilitated the accurate diagnosis of the infection and of the extent of involvement. Early recognition with appropriate antibiotics in the pre-suppurative stage and prompt surgical intervention in the late stages form the corner stone of treatment. Delay in diagnosis can result in increased morbidity and mortality, especially in diabetics and immunocompromised state. Here, we report a case of primary paraspinal pyomyositis in a middle-aged female and emphasize the importance of early diagnosis and treatment.
