Intracranial venous aneurysms: vein of Galen and other similar vascular anomalies.
Aneurysmal dilatation of the vein of Galen is peculiar to arteriovenous malformation around the midbrain. Similar venous aneurysms may rarely occur in other regions. This paper deals with the radiographic findings in three cases of vascular malformation associated with giant venous aneurysms. The pathophysiology resulting in aneurysmal venous dilatation is discussed based on our material and those previously reported.
