Abstract
Pyomyositis is a subacute, deep bacterial infection of skeletal muscles. Originally described
in tropical areas, mainly in malnourished and immunocompromised subjects
(“tropical pyomyositis”), it has been subsequently reported with an increasing frequency
also in temperate climates. Larger muscle groups located in the pelvic girdle and in the
lower extremities (including the thigh, calf and gluteal muscles) are most commonly affected,
but any muscle group can be involved. S. aureus is the most common causative
agent, being responsible for up to 90% of tropical cases and up to 75% of cases in temperate
areas. Local trauma as a predisposing factor is reported in up to 39% of cases.
There are no specific laboratory tests for pyomyositis. MRI is the gold standard for the
diagnosis. Treatment of pyomyositis largely depends on the stage of the disease. Prompt
intravenous antibiotic therapy targeted on Staphylococcus aureus is generally effective
for early infections. Both antibiotic therapy and drainage are necessary in more advanced
stages. The paper reports one of muscle gluteus maximus involvement, reviews the
literature and describes the experience with pyomyositis at Institute for Maternal and
Child Health IRCCS “Burlo Garofolo” (Trieste, Italy) over the past ten years.
