Summary
Homocystinuria, a metabolic disorder, causes significant skeletal abnormalities in children. Roentgenological evaluation revealed widespread bone changes, particularly osteoporosis, in the spine and growth areas.
Area of Science:
- Medical Genetics
- Pediatric Radiology
- Biochemical Disorders
Background:
- Homocystinuria is an autosomal recessive disorder of sulfur amino acid metabolism.
- It is clinically characterized by lens dislocation, intellectual disability, skeletal abnormalities, and thromboembolic events.
Purpose of the Study:
- To radiologically evaluate and characterize skeletal abnormalities in pediatric patients with homocystinuria.
Main Methods:
- Retrospective analysis of roentgenological findings in 12 pediatric patients diagnosed with homocystinuria.
- Focus on identifying specific bone changes and their locations.
Main Results:
- Widespread skeletal abnormalities were detected in all patients.
- Key findings include osteoporosis, dolichostenomelia, arachnodactyly, and calcific spicules in wrist physes.
- Abnormalities were most prominent in the dorsolumbar spine and epi-metaphyseal growth areas.
Conclusions:
- Cystathionine synthase deficiency (homocystinuria) leads to significant and widespread skeletal manifestations in children.
- Radiological assessment is crucial for identifying these bone changes, aiding in diagnosis and management.
