Sonography of musculoskeletal infection in children

Area of Science:

• Pediatric Radiology
• Musculoskeletal Imaging
• Infectious Diseases

Background:

• Musculoskeletal infections in children often present with vague symptoms, requiring prompt imaging.
• Magnetic Resonance Imaging (MRI) is ideal for bone infection but is costly and may need anesthesia in young patients.
• Ultrasound offers a readily available, radiation-free imaging modality for initial assessment.

Purpose of the Study:

• To review the sonographic features of pediatric musculoskeletal infections.
• To highlight the advantages and limitations of ultrasound in this context.
• To guide clinicians in utilizing ultrasound for suspected pediatric infections.

Main Methods:

• Review of existing literature on pediatric musculoskeletal infections and ultrasound.
• Description of sonographic findings for septic arthritis, osteomyelitis, pyomyositis, and soft tissue infections.
• Discussion of ultrasound's role in guiding aspiration and drainage.

Main Results:

• Ultrasound effectively visualizes soft tissue and joint effusions, aiding in diagnosing septic arthritis and soft tissue infections.
• Sonography can detect periosteal elevation and intramedullary changes suggestive of osteomyelitis.
• Ultrasound is crucial for guiding needle aspiration and drainage, improving diagnostic yield and therapeutic outcomes.

Conclusions:

• Ultrasound is a versatile, cost-effective imaging tool for the initial evaluation of suspected musculoskeletal infections in children.
• Its portability, lack of ionizing radiation, and utility in guiding procedures make it advantageous, especially when MRI is not readily available or feasible.
• Understanding sonographic features is key to leveraging ultrasound's full potential in pediatric musculoskeletal infection diagnosis and management.
