Acute ischemic stroke caused by compression of the artery of Percheron by arachnoid cyst
View abstract on PubMed
Summary
This summary is machine-generated.Pediatric ischemic stroke is rare, but this case highlights an intraventricular arachnoid cyst causing acute stroke by compressing the artery of Percheron. Urgent endoscopic fenestration and antiplatelet therapy led to full recovery.
Area Of Science
- Pediatric Neurology
- Neuroimaging
- Vascular Neurology
Background
- Ischemic stroke is an uncommon presentation of intracranial mass lesions in children.
- Arachnoid cysts rarely cause vascular events, with only three prior reported cases.
- Intrasellar tumors like pituitary adenomas and craniopharyngiomas are more frequently associated with pediatric ischemic stroke.
Purpose Of The Study
- To report a unique case of a pediatric intraventricular arachnoid cyst presenting as an acute ischemic stroke.
- To illustrate the mechanism of stroke secondary to compression of the artery of Percheron by an arachnoid cyst.
- To highlight the successful management and outcome of such a rare presentation.
Main Methods
- Case report of a pediatric patient with an intraventricular and intracisternal arachnoid cyst.
- Neuroimaging to identify cyst location and vascular compression.
- Urgent endoscopic fenestration and medical management with antiplatelet agents.
Main Results
- A pediatric patient presented with symptoms of acute ischemic stroke, including diplopia, facial nerve palsy, ataxia, and paralysis of upward gaze.
- The ischemic stroke was attributed to compression of the artery of Percheron by an intraventricular arachnoid cyst.
- The patient experienced a full clinical recovery following urgent endoscopic fenestration and antiplatelet therapy.
Conclusions
- Intraventricular arachnoid cysts, though rare, can present as ischemic stroke in children.
- Compression of the artery of Percheron is a potential mechanism for stroke in cases of arachnoid cysts.
- Prompt surgical intervention and medical management can lead to favorable outcomes in this rare condition.
