title: Penetration of the optic nerve and falciform ligament by an internal carotid artery-ophthalmic artery aneurysm: case report.
abstract: We report a case of an internal carotid artery (ICA)-ophthalmic artery aneurysm with penetration of the opticnerve. In addition, this case penetrated the falciform ligament, which severely disturbed optic canal unroofing during surgery. This is the first reported case in which penetration of the optic nerve and falciform ligament has been shown. To remove the anterior clinoid process in this case, the ultrasonic bone curette was a useful tool.
