case_images: (a) Computed tomography revealing diffuse subarachnoid hemorrhage. (b) 3D-reconstruction of digital subtraction revealing a broad base small aneurysm of the basilar tip. (c) Digital subtraction angiography revealing quite high basilar tip in relation to the dorsum sella. (d) Postoperative digital subtraction angiography revealing the total obliteration of the aneurysm

case_images: Computed tomography (CT) and CT angiography revealed a diffuse SAH and ruptured basilar tip aneurysm [Figure 1a]. Digital subtraction angiography (DSA) confirmed the diagnosis of a basilar bifurcation aneurysm with a wide neck and shallow dome [Figure 1b]. The basilar bifurcation was noted to be quite high in relation to the dorsum sella [Figure 1c]. A postoperative angiogram showed the total obliteration of the aneurysm [Figure 1d].

case_images: Preoperative computed tomography-angiography (a) and digital subtraction angiography (b) revealing right posterior communicating artery-posterior cerebral artery and left P1 segment aneurysms. Postoperative intravenous-digital subtraction angiography (c, d) revealing the total obliteration of the aneurysm with presentation of the P1 perforating branch

case_images: CT angiography and a four-vessel angiogram revealed a PComA-PCA junction aneurysm on the right hemisphere and P1 segment aneurysm on the left side [Figure 2a and b]. The patient refused to undergo postoperative arterial DSA, so intravenous-DSA was performed and revealed the total obliteration of the aneurysm [Figure 2c and d].
