The moyamoya phenomenon with accompanying intracranial aneurysm
Neuroradiology
|January 1, 1978
Abstract:
Three cases illustrating the moyamoya phenomenon and an aneurysm in the periphery of the lateral ventricle in angiograms are reported. The mechanism of occurrence of an aneurysm in the moyamoya phenomenon is discussed.
Insights
This report details three cases of moyamoya phenomenon with peripheral lateral ventricle aneurysms. The study discusses the potential mechanisms behind aneurysm formation in moyamoya disease.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Moyamoya disease is a rare, progressive cerebrovascular disorder characterized by stenosis or occlusion of the terminal internal carotid arteries and the development of collateral circulation.
- Aneurysms are abnormal bulging or ballooning of a blood vessel wall, which can rupture and cause hemorrhage.
Observation:
- Three patients presented with the characteristic findings of moyamoya phenomenon on angiograms.
- In all three cases, aneurysms were identified in the periphery of the lateral ventricle.
Findings:
- The co-occurrence of moyamoya phenomenon and peripheral lateral ventricle aneurysms was observed.
- The study explores the potential pathophysiological mechanisms linking moyamoya disease to the formation of these specific aneurysms.
Implications:
- Understanding the mechanism of aneurysm formation in moyamoya disease is crucial for accurate diagnosis and treatment planning.
- This case series may contribute to improved management strategies for patients with moyamoya phenomenon and associated aneurysms.
