Primitive trigeminal artery variant associated with intracranial ruptured aneurysm and cerebral arteriovenous malformation--case report.
A 48-year-old female presented with a unique combination of ruptured aneurysm of the right middle cerebral artery (MCA) manifesting as sudden loss of consciousness associated with arteriovenous malformation (AVM) in the right parietal lobe and left primitive trigeminal artery (PTA) variant. Angiography revealed the right MCA aneurysm, AVM fed by the right anterior cerebral artery and MCA, and contralateral PTA variant. The PTA variant was an anomalous posterior cerebral artery originating from the ipsilateral cavernous internal carotid artery. The neck of the aneurysm was successfully clipped and the AVM was totally removed.
