We describe the incidence of the carotico-clinoid foramen, interclinoid osseous bridge, and pneumatization of the anterior clinoid process (ACP) during surgery for an unruptured paraclinoid aneurysm. We retrospectively analyzed a total of 126 sides of 63 paraclinoid aneurysm cases that underwent extradural anterior clinoidectomy using multidetector-row computed tomography to produce 0.5-mm thick scans. The carotico-clinoid foramen was observed in 15.9% of cases (9.5% unilateral, 6.3% bilateral). The interclinoid osseous bridge was observed unilaterally in 1.6% of cases. Pneumatization of the ACP was observed in 27.0% of cases (22.2% unilateral, 4.8% bilateral). <br> We describe the problems and technical aspects of such cases when performing extradural anterior clinoidectomy. <br>
