39-year-old man with sudden onset of severe headaches, nausea, and vomiting who was found to have subarachnoid hemorrhage and an aneurysm of the left superior cerebellar artery (SCA).

A, Left vertebral arteriogram (anteroposterior view) shows a small aneurysm on a hemispheric branch of the right SCA.

B, Selective right SCA arteriogram (anteroposterior view) better shows the aneurysm.

C, Postprocedural right SCA arteriogram (anteroposterior view) shows occlusion of the hemispheric branch and the aneurysm. Five 2-mm straight coils were used for occlusion. Note some retrograde filling of the occluded branch.

D, Left vertebral arteriogram (anteroposterior view) obtained 3 months after coil occlusion shows the aneurysm remains occluded.
