Saccular aneurysm of infancy and early childhood
Insights
This report details a rare pediatric intracranial saccular aneurysm case presenting with sudden neurological deficits. Surgical clipping led to a good recovery, highlighting the distinct nature of childhood aneurysms compared to adult cases.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Intracranial saccular aneurysms are rare in early childhood.
- Pediatric aneurysms present unique clinical and pathological characteristics compared to adult counterparts.
- Sudden onset neurological deficits like dysphasia and hemiplegia can indicate a serious underlying vascular event in children.
Purpose of the Study:
- To report a rare case of intracranial saccular aneurysm in a young child.
- To review the existing literature on pediatric intracranial aneurysms.
- To discuss the distinct pathogenesis and clinical presentation of aneurysms in infants.
Main Methods:
- Case report of a child with intracranial saccular aneurysm.
- Literature review of pediatric intracranial aneurysms.
- Analysis of clinical presentation, treatment, and outcomes.
- Pathological examination of the aneurysm specimen.
Main Results:
- A rare case of intracranial saccular aneurysm in early childhood presented with acute dysphasia and hemiplegia.
- Despite severe preoperative deficits, the patient achieved a good recovery after aneurysm clipping.
- Literature review confirmed the rarity of such lesions, predominantly affecting males under 2 years old.
- Infant aneurysms show different distribution and lack inflammatory or atherosclerotic changes seen in adults.
Conclusions:
- Pediatric intracranial saccular aneurysms are rare and distinct from adult lesions.
- Early diagnosis and surgical intervention, such as clipping, can lead to favorable outcomes even with significant deficits.
- The pathogenesis of childhood aneurysms appears to differ from adult saccular aneurysms, suggesting distinct etiological factors.
Abstract:
A case of intracranial saccular aneurysm occurring in early childhood and presenting with sudden dysphasia and hemiplegia is reported. A review of the literature emphasizes the rarity of this lesion. Despite a significant preoperative neurological deficit, the patient tolerated aneurysm clipping and recovered well. The majority of reported cases involve males under 2 years old. Aneurysms in infants have a distribution different from that seen in adults. Microscopic examination of these lesions fails to show any evidence of inflammation or atherosclerosis. The data suggest that the pathogenesis of these rare childhool lesions differs from that of adult saccular aneurysms.
