3. Figure 2
A 39-year-old patient with history of hypertension and smoking presented with a severe headache and irritability. Four-vessel angiogram (A and B) revealed a trilobed basilar apex aneurysm. A pterional craniotomy with orbito-zygomatic extension was used for surgical exposure. The posterior communicating artery had to be divided to visualize all the lobes. After a difficult dissection, all the lobes of the aneurysm could be occluded completely with long straight clips (C and D).

4. Figure 3
Coronal magnetic resonance imaging (A and B) as well as four-vessel cerebral angiogram (C) depict a giant, thrombosed, posteriorly directed basilar tip aneurysm. The patient underwent a transcavernous approach, and posterior clinoidectomy was performed. Postoperative angiogram (D) shows complete obliteration of aneurysms.

5. Figure 4
A 65-year-old woman presented with poor Hunt and Hess grade (Grade 3). Plain and contrast computed tomography of the head (A) revealed a large basilar apex aneurysm with hydrocephalus. Four-vessel angiogram showed (B) a large basilar apex aneurysm directed superiorly. The patient underwent a pterional craniotomy, half-and-half approach, and the aneurysm was clipped. Postangiogram lateral (C) and oblique (D) views showed complete obliteration of aneurysm. The patient died 10 days later of a ruptured abdominal aortic aneurysm.
