Ischemic tolerance of the sacrifice of AICA is controversial. We report a rare case of ruptured distal AICA aneurysm treated by intra-aneurysmal embolization preserving the AICA trunk.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 77-year-old woman presented with a sudden headache and computed tomography showed a subarachnoid hemorrhage predominant in the left cerebellopontine angle. Cerebral angiography revealed a saccular aneurysm in the anterior pontine segment of the left AICA. Coil embolization underwent preserving the parent artery. There is no recanalization of the aneurysm at 26 months postoperatively. In this case, hemodynamic stress was suggested to be involved in the development of the aneurysm.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>For
