Pyogenic sacroiliitis in children-a diagnostic challenge

Area of Science:

• Pediatric infectious diseases
• Musculoskeletal infections
• Radiology in pediatrics

Background:

• Pyogenic sacroiliitis is a rare pediatric osteoarticular infection (1-2% of cases).
• Deep anatomical location and nonspecific symptoms often delay diagnosis.
• Significant morbidity is associated with osteoarticular infections in children.

Purpose of the Study:

• To describe clinical and radiological features of pediatric pyogenic sacroiliitis.
• To highlight the possibility of early diagnosis through specific patterns.
• To report outcomes of conservative management.

Main Methods:

• Retrospective review of 11 pediatric cases over 8 years.
• Clinical assessment and radiological evaluation (MRI and/or bone scintigraphy).
• Identification of causative agents and treatment strategies.

Main Results:

• A cluster of 4 cases occurred in the last 11 months.
• Staphylococcus aureus was the only identified pathogen.
• All patients, including those with abscesses, responded well to antibiotic therapy alone.

Conclusions:

• Early diagnosis of pyogenic sacroiliitis is feasible with characteristic clinical and imaging findings.
• Conservative antibiotic management is effective for pediatric pyogenic sacroiliitis.
• An algorithm for prompt diagnosis is proposed, though optimal therapy requires further definition.
