52-year-old female with history of coiling right MCA artery, anterior temporal artery, and basilar artery aneurysms. Follow-up for progression. Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.The patient is status-post stent-assisted coiling of basilar tip aneurysm. There is no MRA evidence for aneurysm recurrence.The previously demonstrated left clinoidal segment aneurysm present measuring 4 mm in size is better appreciated on the comparison MRI, however appears stable when compared to the prior exam. A 2-mm right clinoidal segment aneurysm is also stable.The right m1 segment, clipped MCA aneurysm, and anterior temporal artery origin from the former base of the MCA aneurysm is obscured by metal artifact.
1.No MRA evidence for recurrence of basilar tip aneurysm.2.Stable clinoidal segment aneurysms bilaterally.3.The patient's right middle cerebral artery aneurysm is not evaluated on this exam due to metal artifact
