Pyogenic sacroiliitis, the missed diagnosis?

Area of Science:

• Pediatric infectious diseases
• Pediatric orthopedics
• Diagnostic imaging in children

Background:

• Pyogenic sacroiliitis is an uncommon infection in children.
• Diagnosis is frequently delayed due to vague symptoms and normal initial radiographs.
• It can lead to significant morbidity if not identified promptly.

Purpose of the Study:

• To review cases of pediatric pyogenic sacroiliitis.
• To evaluate the utility of isotope bone scanning for early diagnosis.
• To discuss the role of various imaging modalities in detecting this condition.

Main Methods:

• Retrospective review of nine pediatric cases of sacroiliitis over seven years.
• Analysis of diagnostic methods used, including plain radiographs and isotope bone scanning.
• Comparison of imaging findings and clinical presentations.

Main Results:

• Isotope bone scanning proved useful for early diagnosis of pyogenic sacroiliitis.
• Plain radiographs were often normal at presentation, contributing to diagnostic delays.
• Pelvic X-rays, when routinely obtained for hip pain, aided in detection.

Conclusions:

• Isotope bone scanning is a valuable tool for the early diagnosis of pyogenic sacroiliitis in children.
• Routine pelvic imaging in children with hip pain may increase the frequency of detecting pyogenic sacroiliitis.
• Prompt diagnosis and treatment are crucial to minimize complications.
