Abstract
Purulent Infection Myositis (PIM) which was formerly called as tropical myositis is an acute or sub-acute primary infection of striated muscles. It affects all age groups, both sexes and occurs in tropical as well as temperate climates. Most frequently encountered culprits are skin commensals like staphylococci aureus. It is predominantly reported in immunocompromised individuals and with pre-existing muscle abnormalities like strain, trauma, parasite or another inciting event. Gram-negative bacilli myositis in an immunocompetent individual is rare. We report a case of Escherichia coli PIM in an immunocompetent patient with no risk factors and muscle abnormality. This helps early consideration of proper antibiotic therapy in an immunocompetent patient with pyomyositis and helps avoid complications associated with pyomyositis.
Highlights
Purulent Infectious Myositis (PIM) is a subacute purulent infection of the skeletal muscles (Crum-Cianflone, 2008)
Purulent infection myositis is formation of pus in intermuscular planes most commonly encountered during bacteraemia by gram positive organisms
There are multiple hypotheses proposed for the pathogenesis of PIM
Summary
Purulent Infectious Myositis (PIM) is a subacute purulent infection of the skeletal muscles (Crum-Cianflone, 2008). Extensive PIM is most commonly affects the immunocompromised individual with staphylococcus aureus as the most common etiologic agent identified (Habeych et al, 2020). A 34 years lady with no previous known comorbidities presented to our institute with complaints of pain in all limbs for 7 days duration following development of furuncle over left buttock 12 days back for which she didn’t take any medications.
