Methods and Materials
We reviewed the cases of pyomyositis have been presented in the last six years in our hospital.
The clinical findings,
laboratory results and diagnostic imaging studies were included in the analysis.
All children had at least one US examination.
Both MRI and US were available in 6 children.
The diagnosis of suspected lesions was performed using B-mode ultrasound and color Doppler.
Subsequently,
the study is completed with MR imaging by axial,
coronal and sagittal T1-weighted sequences,
T2-weighted sequences,
STIR and diffusion.
In all patients gadolinium IV was administered.
Pyomyositis was classified in three stages,
(1) Invasive stage: which causes the muscle to become edematous and painful,
(2) Suppurative stage: is characterized by formation of an abscess.
(3) Late stage: involves systemic spread of the infection,
leading to septicemia,
multifocal or extensive abscesses,
and shock.
