We report the case of a 51-year-old female who presented with SAH due to a ruptured vasa corona pseudoaneurysm, with no associated anatomical abnormalities involving the vertebral artery or the posterior inferior cerebellar artery. She recovered after direct surgery. In previous cases, anterior spinal artery dilatation due to posterior inferior cerebellar artery anomalies prompted endovascular treatment. A thorough assessment remains crucial, and direct surgery can be effective.<\/jats:p>","DOI":"10.1007\/s00701-025-06531-6","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T05:32:45Z","timestamp":1745299965000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A case of vasa corona ruptured pseudoaneurysm: case report and review of literature"],"prefix":"10.1007","volume":"167","author":[{"given":"Hikaru","family":"Nakamura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsuyoshi","family":"Izumo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuaki","family":"Okamura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shota","family":"Yoshimura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nozomi","family":"Ueki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiro","family":"Baba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenta","family":"Ujifuku","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoichi","family":"Morofuji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Hiu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichi","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayuki","family":"Matsuo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,4,22]]},"reference":[{"key":"6531_CR1","doi-asserted-by":"crossref","unstructured":"Chen CC, Bellon RJ, Ogilvy CS, Putman CM (2001) Aneurysms of the lateral spinal artery: report of two cases.
