Bilateral internal carotid artery agenesis in a child with psychomotor developmental delay
Pediatric Neurology
|July 1, 1996
Insights
A rare balanced translocation, t-(1;3)(p31.2;p21), was identified in a boy with developmental delay and facial differences. The study also diagnosed bilateral internal carotid artery agenesis, a significant finding in pediatric neurology.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Investigating the genetic and vascular underpinnings of severe psychomotor developmental delay.
- Examining rare chromosomal abnormalities and their association with neurological deficits.
Observation:
- A 2-year-old boy presented with severe psychomotor developmental delay and dysmorphic facial features.
- Chromosome analysis revealed a balanced translocation: 46XY,t-(1;3)(p31.2;p21).
- Magnetic resonance angiography identified bilateral internal carotid artery agenesis.
Findings:
- The balanced translocation t-(1;3)(p31.2;p21) was confirmed.
- Bilateral internal carotid artery agenesis was diagnosed as a key vascular anomaly.
- T2-weighted imaging showed periventricular high-intensity areas, but no major cerebral malformations were detected.
Implications:
- This case highlights a potential link between the specific balanced translocation and vascular development anomalies.
- Understanding such rare genetic and vascular conditions is crucial for accurate diagnosis and prognosis in pediatric developmental disorders.
- Further research may elucidate the pathogenic mechanisms connecting chromosomal aberrations to internal carotid artery agenesis.
Abstract:
In a 2-year-old boy with severe psychomotor developmental delay and a dysmorphic face, a chromosome study revealed a balanced translocation: 46XY,t-(1;3)(p31.2;p21). With magnetic resonance angiography, bilateral internal carotid artery agenesis was diagnosed. Periventricular high-intensity areas were evident on T2-weighted imaging, but no major cerebral malformation was observed.
