The Acutely Limping Preschool and School-Age Child: An Imaging Perspective

Area of Science:

• Pediatric Radiology
• Musculoskeletal Imaging

Background:

• Acute limp in children is a common clinical presentation with diverse etiologies.
• Diagnostic challenges arise from difficulties in obtaining adequate clinical history and physical examination in younger children.
• Reliance on imaging is significant for accurate diagnosis of acute limp.

Purpose of the Study:

• To describe the imaging appearance of common causes of acute limp in ambulatory children aged 1-12 years.
• To familiarize radiologists with specific imaging findings for entities causing acute limp.
• To provide guidance on appropriate and judicious imaging strategies for pediatric acute limp.

Main Methods:

• Review article synthesizing imaging characteristics of common etiologies of acute limp.
• Focus on preschool (1-5 years) and school-age (5-12 years) pediatric populations.
• Discussion of conditions affecting the hip, spine, abdomen, pelvis, and knee.

Main Results:

• Detailed description of imaging findings for various causes of acute limp.
• Emphasis on differentiating conditions with potential for rapid deterioration, such as septic hip and osteomyelitis.
• Correlation of imaging findings with specific clinical entities.

Conclusions:

• Accurate interpretation of imaging is crucial for diagnosing the cause of acute limp in children.
• Understanding the imaging spectrum of common etiologies aids in timely and appropriate patient management.
• Judicious use of imaging resources is essential for effective evaluation of pediatric acute limp.
