We reported the first VS RRA case admitted for acute anterior inferior cerebella artery (AICA) ischemic symptoms. Literature was reviewed to present the research fruits about VS RRAs, and some therapeutic advices were given.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>A 54-year-old woman who had undergone GKS 10 years previously for a right VS was admitted to our hospital in 2018 because of sudden onset of severe vertigo and vomiting, accompanied with unsteady gait. During tumor resection, a dissecting aneurysm arose from the main trunk of AICA was encountered accidently within the tumor. The aneurysm was successfully treated with direct clip ligation, sparing the parent vessel. Data about this case were combined with those of other 11 radiation-related AICA aneurysm cases retrieved from the current literature. The following parameters were evaluated: Age, Sex, Diagnostic method, Location of aneurysm, Age of radiotherapy (Years)\/Latency, Rupture, x-ray dosage, Type of radiotherapy, History of surgical resection of VS, Aneurysm Type, Morphology, Number, Treatment, Operative complications, Sequela, Outcome. VS RRAs mainly occurred in women (75%) with a median age of 62.5 years and were mainly located on AICA. Ruptured aneurysms accounted for 75.0% of the total cases. This paper reported the first VS case admitted with acute AICA ischemic symptoms. Cases with sacciform-like, irregular and fusiform-shaped aneurysms accounted for 50.0%, 25.0% and 25.0% of the total, respectively. After surgical treatment, 75.0% patients recovered, except for 3 patients who developed new ischemic consequence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Patients should be informed of the risk of RRAs after receiving radiotherapy for VS. In these patients, RRAs should be suspected when subarachnoid hemorrhage or AICA ischemic symptoms occurred. Active intervention should be conducted considering the high instability and bleeding rate of VS RRAs.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fsurg.2023.1082265","type":"journal-article","created":{"date-parts":[[2023,2,9]],"date-time":"2023-02-09T06:59:07Z","timestamp":1675925947000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Unruptured anterior Inferior cerebellar artery aneurysm following stereotactic irradiation for vestibular schwannoma: Case report and literature review"],"prefix":"10.3389","volume":"10","author":[{"given":"Denghui","family":"Lu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoda","family":"Ping","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunze","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingxi","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yafei","family":"Xue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Qu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianzhi","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,2,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"102","DOI":"10.1177\/0194599818765717","article-title":"National trends in vestibular schwannoma surgery: influence of patient characteristics on outcomes","volume":"159","author":"Hatch","year":"2018","journal-title":"Otolaryngol Head Neck Surg"},{"key":"B2","doi-asserted-by":"publisher","first-page":"60","DOI":"10.1016\/j.wneu.2016.10.066","article-title":"Gamma knife radiosurgery for residual and recurrent vestibular schwannomas after previous surgery: clinical results in a series of 90 patients and review of the literature","volume":"98","author":"Bailo","year":"2017","journal-title":"World Neurosurg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"540","DOI":"10.1016\/j.wneu.2017.02.041","article-title":"Gamma knife radiosurgery for low-grade gliomas: clinical results at long-term follow-up of tumor control and Patients\u2019 quality of life","volume":"101","author":"Filippo","year":"2017","journal-title":"World Neurosurg"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1317","DOI":"10.1007\/s00701-006-0912-4","article-title":"Ruptured intracranial aneurysm following gamma knife surgery for acoustic neuroma","volume":"148","author":"Takao","year":"2006","journal-title":"Acta Neurochir"},{"key":"B5","doi-asserted-by":"publisher","first-page":"543","DOI":"10.3171\/2008.8.JNS08177","article-title":"Ruptured pseudoaneurysm following gamma knife surgery for a vestibular schwannoma","volume":"110","author":"Akamatsu","year":"2009","journal-title":"J Neurosurg"},{"key":"B6","doi-asserted-by":"publisher","first-page":"202","DOI":"10.2176\/nmc.49.202","article-title":"Ruptured distal anterior inferior cerebellar artery aneurysm following stereotactic irradiation for vestibular schwannoma: case report","volume":"49","author":"Yamaguchi","year":"2009","journal-title":"Neurol Med Chir"},{"key":"B7","doi-asserted-by":"publisher","first-page":"540","DOI":"10.3171\/2008.9.JNS08860","article-title":"De novo intracranial aneurysm formation after gamma knife radiosurgery for vestibular schwannoma","volume":"110","author":"Park","year":"2009","journal-title":"J Neurosurg"},{"key":"B8","doi-asserted-by":"publisher","first-page":"536","DOI":"10.3109\/02688697.2013.847168","article-title":"Development of anterior inferior cerebellar artery pseudoaneurysm after gamma knife surgery for vestibular schwannoma.
