A 54-year-old woman with 3 untreated additional aneurysms unchanged after 5 years. A and B, Right internal carotid angiogram (A) and vertebral angiogram (B) show additional aneurysms on the carotid cavernous sinus, middle cerebral artery, and superior cerebellar artery (arrows). C, MRA after 5 years demonstrates unchanged size of all 3 aneurysms (arrows).

A 25-year-old woman with multiple additional untreated aneurysms. A, Initial lateral view of an internal carotid angiogram shows a 1.5-mm pericallosal artery aneurysm. B, Five-year follow-up MRA reveals growth to 2.5 mm. C, Angiogram confirms MRA findings.

A 56-year-old woman with a de novo 3-mm middle cerebral artery aneurysm. A, Initial angiogram of the middle cerebral artery. B, MRA after 5 years shows 3-mm de novo aneurysm (arrow).
- Fig 5.
Five-year MRA follow-up in a 42-year-old woman with a coiled right middle cerebral artery aneurysm demonstrates 2 left middle cerebral artery aneurysms and a superior cerebellar artery aneurysm (arrows) without available previous imaging. The 2 middle cerebral artery aneurysms were clipped.
