MRA demonstrates an azygos anterior cerebral artery, with no associated aneurysms. On the right, a small persistent trigeminal artery contributes to the vertebra basilar system which is generally diminutive in size. The right posterior cerebral artery is foetal in origin. Otherwise intracranial circulation is unremarkable.
