A 54-year-old woman was admitted to our hospital because of severe headache. CT scan demonstrated subarachnoid hemorrhage (SAH), and cerebral angiography revealed a wide-necked basilar tip aneurysm with a bleb and a small basilar artery-left superior cerebellar artery aneurysm. She was treated with coil embolization using a neck remodeling technique one day after SAH. ⋯ Angiography immediately after the procedure showed complete occlusion of the aneurysm with patency of both PCAs. The Hyperform occlusion balloon is very compliant and supple, so it easily changes from its cylindrical shape when inflated to expand into the origin of the arterial branches emerging from the aneurysm neck. We think this balloon is a useful device for treating wide-necked aneurysms located at arterial bifurcation.

Case Reports
[A case report of ruptured internal carotid artery aneurysm with contralateral oculomotor nerve paresis].
We report a case of ruptured internal carotid artery aneurysm with contralateral oculomotor nerve paresis. A 69-year-old female experienced a sudden onset of severe headache. Left-sided mydriasis, absence of light reflex, disability of left ocular movement and ptosis were identified. ⋯ The oculomotor nerve paresis lasted for ten days. Ruptured right internal carotid artery aneurysm was surgically confirmed and repaired. We speculated that the contralateral oculomotor nerve paresis was the consequence of bloody jet flow from the ruptured aneurysm.
