Insights
Post-traumatic cyst-like lesions in children are rare, typically appearing 1.5-3 months after a distal radius greenstick fracture. These benign lesions are asymptomatic and resolve on their own.
Area of Science:
- Pediatric Orthopedics
- Pediatric Radiology
- Pediatric Bone Pathology
Background:
- Post-traumatic cyst-like lesions are uncommon findings in pediatric patients.
- These lesions are typically observed following skeletal trauma, particularly greenstick fractures.
Observation:
- Lesions manifest 1.5 to 3 months post-fracture, most commonly after distal radius fractures.
- Radiographic findings include a metaphyseal radiolucent lesion within new subperiosteal bone, adjacent to the fracture line.
Findings:
- The described lesions are benign, asymptomatic, and non-expansive.
- Spontaneous regression of these post-traumatic lesions is characteristic.
Implications:
- Understanding the typical presentation aids in accurate diagnosis and management of pediatric bone lesions.
- Recognition of spontaneous resolution avoids unnecessary interventions for these benign entities.
Abstract:
Reports of post-traumatic cyst-like lesions in children are rare. These lesions occur between 1.5 and 3 months after a fracture. They are more frequent after a distal radius greenstick fracture. Conventional radiographs show a metaphyseal radiolucent lesion inside the most recent subperiosteal bone, adjacent to the initial fracture line. Post-traumatic cyst-like lesions are benign, asymptomatic, nonexpansive, and regress spontaneously. Two typical cases are described in the following report with a literature review of the etiology and main features of these lesions.
