Pyomyositis of Gluteus medius: A case report and review of the literature

Introduction We present a case of 12 year old boy presented with right hip pain, fever and antalgic gait. Inflammatory markers were raised at presentation. The pelvic radiograph and ultra sound scan of right hip joint did not detect any abnormality. The Magnetic Resonance Imaging (MRI) scans revealed inflammatory oedema in the right gluteus medius muscle. He was treated with intravenous Flucloxacillin for 10 days and later 6 weeks of oral Flucloxacillin. At the 6 weeks follow up patient was asymptomatic with normal gait. MRI at 6 weeks did not show any fluid collection in gluteus medius. Conclusion Pyomyositis is rare in temperate countries. It must be considered as one of the differential diagnosis in a child presenting with hip pain, fever and raised inflammatory markers.
