a-h. Case 1: a 49-year old female experiencing sudden headache, nausea and vomiting. 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
