Fig 2. A 58-year-old woman with a ruptured superior cerebellar artery aneurysm without a neck. A and B, 2D and 3D vertebral angiograms demonstrate the dysplastic distal basilar segment with a large superior cerebellar artery aneurysm. The superior cerebellar artery arises from base of the aneurysmal sack, and the dysplastic segment extends to the proximal posterior cerebral arteries. C, Result after stent-assisted coiling. Proximal and distal stent markers are indicated by arrows. Flow in the superior cerebellar artery is preserved.
