Conclusion
The pyomyositis is a rare pathologic condition in children and early diagnosis is difficult.
Because clinical and laboratory parameters present low diagnostic sensitivity and specificity for the detection of musculoskeletal infection,
radiology plays an essential role in the early diagnosis,
also allowing detection of the anatomical compartment involved by the infection and there by helping to guide treatment options.
Any muscle group can be affected although the most frequently involved muscles are the following by order of frequency: quadriceps > gluteus and iliopsoas muscles > upper extremity muscles.
Patients are often otherwise healthy,
but may have a history of trauma or immunosuppression.
We found history of trauma in 3 patients and history of immunosuppression in 2 patients.
The pyomyositis classification is useful in the clinical and radiological correlation.
Ultrasoud is very useful for the early diagnosis of the pyomiositis.
MRI confirms the diagnosis,
evaluate the local extension and allows to despicte bone affection. Ultrasound is the fastest option available for us,
used for initial diagnosis,
monitoring and guide to drainage if it is necessary.
