Psoas abscess associated with renal pathology in children

Area of Science:

• Pediatric infectious diseases
• Nephrology
• Surgical pathology

Background:

• Pyogenic psoas abscess in children is predominantly a primary condition.
• Staphylococcus aureus is the most frequent causative agent in primary psoas abscesses.
• Secondary psoas abscesses, often linked to contiguous spread, are less common in pediatric populations.

Purpose of the Study:

• To describe three pediatric cases of secondary psoas abscess.
• To investigate the association between secondary psoas abscess and underlying renal pathology.
• To differentiate the etiology from common primary psoas abscesses in children.

Main Methods:

• Case series review of pediatric patients diagnosed with psoas abscess.
• Clinical data collection including patient history, diagnostic imaging, and microbiological findings.
• Analysis of associated medical conditions, with a focus on renal pathology.

Main Results:

• Three pediatric patients presented with secondary psoas abscess.
• All three cases were associated with significant underlying renal pathology.
• The causative organisms and specific renal conditions varied among the cases.

Conclusions:

• Secondary psoas abscess in children can arise from underlying renal pathology.
• This presentation is distinct from the more common primary psoas abscesses.
• Early recognition of associated renal abnormalities is crucial for effective management of secondary psoas abscesses.
