Insights
A pediatric giant aneurysm in the internal carotid artery caused headaches and vision loss. Endovascular obliteration led to successful aneurysm regression, confirmed by MRI.
Area of Science:
- Pediatric Neurology
- Vascular Neurosurgery
- Endovascular Therapy
Background:
- Giant aneurysms are rare in children.
- Supraclinoid internal carotid artery aneurysms can present with mass effect symptoms.
- Aneurysms may mimic other suprasellar lesions like craniopharyngioma.
Purpose of the Study:
- To report a case of a partially-thrombosed giant lobulated aneurysm in a pediatric patient.
- To discuss the diagnostic challenges and endovascular management of such cases.
- To highlight the successful outcome of endovascular obliteration and aneurysm regression.
Main Methods:
- Case presentation of a 2-year-old boy with progressive headache and visual loss.
- Diagnostic imaging including CT, revealing a suprasellar mass.
- Successful endovascular obliteration of the aneurysm.
Main Results:
- The lesion was identified as a partially-thrombosed giant lobulated aneurysm.
- Endovascular obliteration was technically successful.
- Follow-up MRI confirmed regression of the aneurysm.
Conclusions:
- Giant aneurysms in the supraclinoid internal carotid artery are a rare but significant cause of neurological deficits in children.
- Endovascular treatment is a viable and effective option for managing pediatric giant aneurysms.
- Prompt diagnosis and intervention can lead to favorable outcomes and regression of the aneurysm.
Summary:
We present the case of a two-year and seven-month-old boy with a partially-thrombosed giant lobulated aneurysm in the supraclinoid portion of the internal carotid artery. He presented with several months of symptoms of progressive frontal headache and visual loss. CT revealed a large lobulated suprasellar mass lesion mimicking a craniopharyngioma. After the aneurysm was successfully obliterated by an endovascular procedure, regression of the giant aneurysm was confirmed on followed-up MRI. The differential diagnosis, possible etiologies, and the endovascular technique for pediatric patient will be discussed.
