(a and b) Head computed tomography (CT) showing thick subarachnoid hemorrhage (SAH), Sylvian hematoma, and acute hydrocephalus. (c and d) Head CT angiography showing right A1 anterior cerebral artery (ACA) aneurysm with bleb and left vertebral artery saccular aneurysm. (e) Head CT angiography on day 7 after SAH showing trapped right A1 ACA aneurysm. The left middle cerebral artery is visualized less clearly than the right middle cerebral artery. (f) Initial common carotid angiography (CCAG) showing dissection of the cervical portion of the left internal carotid artery with delayed distal flow. (g) Internal carotid angiography from the distal lumen of the dissecting lesion. (h) Postoperative CCAG showing the dissecting lesion after carotid stenting.

Head computed tomography (CT) revealed a thick SAH with Sylvian hematoma (Fisher Group 4), and CT angiography (CTA) revealed a fusiform aneurysm of the right A1 segment of the ACA and a saccular aneurysm of the left vertebral artery (VA) [Figure 1].
(a and b) Abdominal computed tomography angiography showing dissecting aneurysms of the celiac artery (a, arrow) and superior mesenteric artery (b, arrow).
