We report a case of subarachnoid hemorrhage(SAH)with multiple cerebral aneurysms, in which magnetic resonance vessel wall imaging(MR-VWI)revealed the rupture site. A 68-year-old woman presented with SAH. Computed tomography(CT)showed diffuse SAH(Fisher group 3). 3D-CT angiography revealed two intracranial aneurysms:a 4.2-mm anterior communicating artery aneurysm(Acom An)and a 5.8-mm basilar tip aneurysm(BAtip An). ⋯ Thus, we performed a craniotomy for the Acom An. Intraoperative findings confirmed the rupture site at the Acom An. We concluded that high resolution MR-VWI may be useful for identifying the rupture site in patients with spontaneous SAH and multiple cerebral aneurysms.
