Summary

Most pediatric pneumatoceles (PCs) resolve spontaneously within two months. Complicated PCs may require image-guided drainage or surgery for persistent symptoms or large size.

Area of Science:

  • Pediatric Pulmonology
  • Thoracic Surgery
  • Infectious Diseases

Background:

  • Postpneumonic empyema is a common complication in children.
  • Pneumatocele (PC) formation can occur secondary to empyema.
  • Understanding the natural history of pediatric PCs is crucial for management.

Purpose of the Study:

  • To determine the natural course of pneumatocele (PC) in children with postpneumonic empyema.
  • To identify appropriate therapeutic strategies for pediatric PCs.

Main Methods:

  • Retrospective review of 134 children treated for postpneumonic empyema.
  • Analysis of chest x-rays and CT scans for 58 children with PCs.
  • Evaluation of clinical course, treatment indications, and outcomes.

Main Results:

  • Of 58 children with PCs, 63.7% resolved spontaneously within 2 months.
  • 13 PCs gradually decreased in size over a mean of 6.1 months without intervention.
  • 7 patients underwent image-guided drainage, with 5 successful outcomes; 3 required surgery due to persistent or complicated PC.

Conclusions:

  • Simple pediatric pneumatoceles (PCs) typically resolve spontaneously with infection improvement.
  • Complicated PCs, indicated by persistent infection, large size, or tension, warrant intervention.
  • Image-guided drainage is effective, but surgical excision may be necessary for refractory cases with thickened walls.
