Abstract:
A 17-year-old boy with type I glycogen storage disease (GSD-I) and a stroke associated with moyamoya disease is described. This is the first report of this association, and only the second reported case of cerebrovascular disease in patients with GSD-I. The relationship of the primary metabolic error and the vascular injury is explored. This represents yet another disorder associated with moyamoya disease, which is considered to be a secondary phenomenon of vascular occlusion that occurs under a specific set of circumstances in a susceptible age group.
Insights
This study reports the first association between type I glycogen storage disease (GSD-I) and moyamoya disease in a teenage patient. It explores the link between metabolic errors and cerebrovascular events in GSD-I patients.
Area of Science:
- Neurology
- Metabolic Disorders
- Pediatrics
Background:
- Type I glycogen storage disease (GSD-I) is a rare inherited metabolic disorder affecting glucose metabolism.
- Moyamoya disease is a progressive cerebrovascular disorder characterized by stenosis of the terminal internal carotid arteries.
Observation:
- A 17-year-old male with a known diagnosis of GSD-I presented with a stroke.
- Imaging revealed findings consistent with moyamoya disease.
- This represents the first documented co-occurrence of GSD-I and moyamoya disease.
Findings:
- The case highlights a potential, previously unreported association between GSD-I and moyamoya disease.
- Cerebrovascular disease is rare in GSD-I patients, with only one other case reported.
- The study explores the potential link between the metabolic derangements in GSD-I and vascular injury.
Implications:
- This association may expand the spectrum of secondary causes of moyamoya disease.
- Further research is warranted to understand the pathophysiological mechanisms connecting GSD-I and cerebrovascular complications.
- Recognition of this association could improve diagnostic and management strategies for patients with GSD-I and neurological symptoms.
