Summary
This study details four cases of lenticulostriate artery aneurysms, a rare condition in young patients. Conservative management is recommended due to treatment challenges and spontaneous thrombosis risk.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Lenticulostriate artery aneurysms are rare cerebrovascular pathologies.
- They often present in young individuals with symptoms like meningeal syndrome or focal neurological deficits.
Observation:
- Four cases are presented: three idiopathic and one associated with MoyaMoya disease.
- Hemorrhage is detected via non-contrast CT or MRI, aiding in assessing its impact.
- Arteriography or MRA are crucial for diagnosing the aneurysm and ruling out vascular malformations.
Findings:
- The study reviews 15 published cases alongside their own experience.
- Surgical or endovascular approaches are often challenging.
- Spontaneous thrombosis of these aneurysms occurs with notable frequency.
Implications:
- Conservative management appears justified for lenticulostriate artery aneurysms after thorough etiological investigation.
- Radio-clinical monitoring is essential for patients undergoing conservative treatment.
- Further research into optimal management strategies for this rare condition is warranted.
