"Popcorn" calcifications: a prognostic sign in osteogenesis imperfecta
Insights
Popcorn calcifications, a sign of disordered bone growth, are common in children with osteogenesis imperfecta. These unique bone lesions indicate issues with enchondral ossification during skeletal development.
Area of Science:
- Pediatric Radiology
- Skeletal Dysplasias
- Pediatric Orthopedics
Background:
- Popcorn calcifications are radiographically described as scalloped radiolucencies with sclerotic margins.
- These calcifications are observed in various skeletal conditions.
Purpose of the Study:
- To investigate the occurrence and characteristics of popcorn calcifications in children with osteogenesis imperfecta.
- To understand the relationship between popcorn calcifications and skeletal growth in osteogenesis imperfecta.
Main Methods:
- Retrospective review of radiographs from 46 children diagnosed with osteogenesis imperfecta.
- Analysis of the location, timing, and association of popcorn calcifications with growth plate morphology.
Main Results:
- Popcorn calcifications were identified in 52% of the children studied.
- These lesions were observed only during active skeletal growth, not at birth.
- Predominant locations included the knees and ankles, associated with irregular or absent growth plates.
Conclusions:
- Popcorn calcifications result from fragmentation and disordered maturation of the physis (growth plate).
- Their presence signifies a disturbance in enchondral ossification.
- This disturbance may contribute to the severe growth retardation seen in osteogenesis imperfecta.
Abstract:
"Popcorn" calcifications appear roentgenographically as a collection of scalloped radiolucencies, each with a sclerotic margin and in some instances, with central densities. The radiographs of 46 children with osteogenesis imperfecta were reviewed retrospectively; 52% had "popcorn" calcifications at one or more sites. A study of these children indicated that these lesions are observed only during active skeletal growth, are not present at birth, occur predominantly around the knees and ankles, and are associated with irregularity or absence of the normal horizontal growth plate. Based on multiple roentgen observations, "popcorn" calcifications appear to result from fragmentation and disordered maturation of the physis, and their presence indicates a disturbance in enchondral ossification which may contribute to the severe growth retardation associated with osteogenesis imperfecta.
