Figure 7 Bony landmarks related to the aneurysm. A: Three-dimensional (3D)-computed tomography angiography shows a posterior communicating artery aneurysm close to the anterior clinoid process; B: 3D-computed tomography (CT) for the skull base shows bridging sella and bony fusion; C: Post-operative 3D-CT shows partial clionoidectomy and metallic clip.
