Case Description: We herein present the case of a patient suffering from a subarachnoid hemorrhage (SAH) with two aneurysms in which the AICA aneurysm was negative by CTA and DSA. CTA demonstrated a right anterior choroidal artery aneurysm, which was revealed to be an unruptured aneurysm after surgical exploration. A small distal AICA aneurysm was detected by 3D rotational angiography (3DRA). The patient fully recovered except for left-side hearing loss four months after the second operation. Conclusion: We recommend a meticulous diagnosis by 3DRA in patients with SAH in which the distribution is not coincident with a typical aneurysmal location.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/277c7995-ab74-4a3d-ad55-ffbf3aa21ff2/featured/hero-1782420876352.png","publishDate":"2015-06-04T00:00:00.000Z","doi":"10.4103/2152-7806.158206","categories":["Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/277c7995-ab74-4a3d-ad55-ffbf3aa21ff2/pdf"}
