Fig 2. Images depicting embolization of the left AICA aneurysm. The bilobed AICA aneurysm was better profiled in oblique view (A). Although the aneurysm was filling well after detachment of the first coil (B), a repeat angiogram after a few minutes shows complete occlusion of the aneurysm (C). Progressive thrombus formation was noticed in a repeat angiogram done after a few minutes, which shows a small thrombus projecting into the basilar artery from the neck of the aneurysm (D).
