Summary
This study reports the first case of cerebrovascular disease in a 13-year-old with purine nucleoside phosphorylase deficiency. The patient experienced neurological issues, including hemiparesis and hemiplegia, indicative of stroke.
Area of Science:
- Neurology
- Genetics
- Immunology
Background:
- Purine nucleoside phosphorylase (PNP) deficiency is a rare genetic disorder affecting the immune system.
- Neurological complications are known in PNP deficiency, but cerebrovascular disease is rarely documented.
Observation:
- A 13-year-old female, the oldest known survivor with PNP deficiency, presented with recurrent neurological deficits.
- Symptoms included transient left hemiparesis and subsequent dense left hemiplegia.
Findings:
- Magnetic resonance imaging confirmed a right internal capsule infarct, indicating a stroke.
- Cerebral angiography revealed vasculopathy affecting the proximal cerebral vessels.
Implications:
- This case highlights cerebrovascular disease as a potential complication of purine nucleoside phosphorylase deficiency.
- Understanding the mechanisms of neurological dysfunction in PNP deficiency is crucial for patient management.
