Basal ganglia calcification in Down's syndrome.
Computerized Tomography
|January 1, 1979
Summary
Basal ganglia calcification is more common in children with Down syndrome. This report details the first in-life diagnosis of basal ganglia calcification in Down syndrome, showing it can occur without movement disorders.
Area of Science:
- Neurology
- Radiology
- Genetics
Background:
- Basal ganglia calcification (BGC) is a rare finding, with an approximate incidence of 0.3% in the general neurological population.
- Autopsy studies indicate BGC occurs in approximately 7% of children with Down syndrome (DS).
Observation:
- This report presents the first documented case of BGC diagnosed during life in a child with Down syndrome.
- The diagnosis was confirmed using computed axial tomography (CT).
Findings:
- The case demonstrates that significant basal ganglia calcification can be present in Down syndrome patients without any clinical signs or symptoms of a movement disorder.
- This challenges the assumption that BGC in this population invariably leads to neurological deficits.
Implications:
- Highlights the importance of neuroimaging in evaluating children with Down syndrome, even in the absence of motor symptoms.
- Suggests further research is needed to understand the relationship between BGC, Down syndrome, and neurological presentation.
- May prompt a re-evaluation of screening protocols for neurological complications in Down syndrome.
