[Ruptured peripheral lenticulostriate artery aneurysm in a child: case report]

Area of Science:

• Neurology
• Neurosurgery
• Pediatric Neurology

Background:

• Intracerebral hematoma and subarachnoid hemorrhage in children are rare but serious conditions.
• Peripheral lenticulostriate artery aneurysms are an uncommon cause of intracranial hemorrhage, especially in pediatric patients.

Observation:

• A 12-year-old female presented with symptoms of intracerebral hematoma and subarachnoid hemorrhage.
• The hemorrhage was attributed to a ruptured peripheral lenticulostriate artery aneurysm.

Findings:

• The patient underwent proximal clipping of the lateral lenticulostriate artery at the middle cerebral artery.
• Continuous ventricular drainage was performed for six days to manage acute hydrocephalus.
• Postoperative angiography confirmed successful obliteration of the aneurysm.

Implications:

• This case represents the first reported instance of a ruptured peripheral lenticulostriate artery aneurysm in childhood.
• The successful surgical management highlights the feasibility of treating such rare aneurysms in pediatric patients.
• Further discussion on the pathogenesis and treatment modalities for these aneurysms is warranted.
