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

Insights
A ruptured peripheral lenticulostriate artery aneurysm caused brain bleeding in a 12-year-old girl. Surgical clipping successfully treated the aneurysm, resulting in a full recovery without neurological deficits.
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.
Abstract:
We report a 12-year-old with intracerebral hematoma and subarachnoid hemorrhage secondary to the rupture of a peripheral lenticulostriate artery aneurysm. We carried out proximal clipping of the lateral lenticulostriate artery at the middle cerebral artery following six days of continuous ventricular drainage for acute hydrocephalus. Postoperative angiography confirmed the obliteration of the aneurysm. The girl was discharged without any neurologic deficits. To our knowledge, this is a first reported case in the literature of a ruptured peripheral lenticulostriate artery aneurysm in childhood. The pathogenesis of such an aneurysm and the treatment modalities are discussed.
