Figure 1: A 52-years-old patient presented with two episodes of loss of consciousness, followed by severe headache and multiple episodes of vomiting. (a) Unenhanced CT showed minimal SAH in the right parietal sulcal space (long arrow). (b) Anteroposterior (left) and lateral (right) angiogram of right common carotid artery injection shows diffusely narrowed caliber (arrow) of the internal carotid artery. (c) Lateral angiogram showing anterior circulation is compensated through PCOA (long arrow). (d) 3D reconstruction angiogram showed flow-related aneurysms in the posterior circulation (arrows) (e) nonsubtracted (left) and subtracted anteroposterior view (right) after unassisted coiling done showing coils (arrow). CT: Computerized tomography, SAH: Subarachnoid hemorrhage, PCOA: Posterior communicating artery, 3D: Three-dimensional.
