Pyomiositis is a rare infective disease that is characterised by suppuration within striated muscles. In recent years pyomyositis has increasingly been diagnosed even in patients without predisposing factors. Early diagnosis is critical for saving the tissue and also the life of patient but is often missed because of unfamiliarity with the disease, atypical presentations, a wide range of differential diagnoses, lack of early specific signs. To evaluate the role of diagnostic techniques in the early diagnosis and therapeutic management of pyomyositis in children.

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...

9 cases of pyomyositis were studied, 5 of which were women and 4 men with ages from 1 to 12 years. The pyomyositis involved the following parts: - Abdomen (n=2); - Pelvis (n=3); - Thigh (n=3); - Neck (n=1). These patients had typical clinical symptoms with increasing size, redness, heat, fever, pain, and malfunction of involved extremities. Laboratory test reveal anaemia, leucocytosis (shift to the left), raised erythrocyte sedimentation rate, and acute phase reactant. Staphylococcus aureus was the organism most commonly cultured from the abscess....

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 ofmusculoskeletal 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...
