Computed Tomography (a) revealed small amount of SAH and some clotting that were restricted to perimesencephalic cisterns. Conventional Computed Tomography Angiography (b) and initial DSA of lateral projection (c) showed a tiny aneurysm (arrow) from the basilar trunk. AICA angiography (d) (arrow) illustrated that the aneurysm was not from anterior inferior cerebellar artery or its branches. e Intraoperative oblique projections of basilar artery showed contrast stagnation. Endovascular balloon (f) was used to occlude parent artery by compressing the origin of the perforator for about 5 min. Complete disappearance of the aneurysm was presented in (g) and in the 2-year follow-up image (h) of basilar angiogram
