Pyomyositis is an infection which involves one or more skeletal muscle groups,
and which is not a result of infection of adjacent skin,
It was originally described in the tropics1. In our poster,
we attempted to describe the findings of Multidetector Computed Tomography of pyomyositis and correlate these data with the clinical information.
Patients are often otherwise healthy,
but may have a history of trauma,
emigration from or recent travel to a tropical area of the world,
intravenous drug abuse,
history of malignancy and diabetes2,3,4.
We did not find history of trauma or emigration.
diabetes and history of malignancy were the most frequent underlying diseases.
Pyomyositis is usually caused by Staphylococcus aureus1,3,4.
We found Staphylococcus aureus the most frequent bacteria (26%).
Lopez and Lartchenko5 described 75%-90%.
We found upper-extremity muscles being affected less frequently,
similar results had been described6.
The most common sites of infection were trunk and lower extremities.
The pyomyositis classification is useful in the clinical and radiological correlation.
Contrast-enhanced CT plays an important role in the early recognition of bacterial PM.
By precisely demarcating the extent of the disease,
good evaluation of joints and bones,
therefore allows planning prompt antibiotic treatment combined with or without interventional procedures.
