The correct diagnosis was established based on surgical exploration. In addition, grayscale modification of 3D reconstruction images of preoperative digital subtraction angiography revealed the cases of the recurrent artery of Heubner and perforating artery of the ACoA arising from the apex of the infundibular widening.<\/jats:p>","DOI":"10.3171\/2013.3.jns122058","type":"journal-article","created":{"date-parts":[[2013,4,19]],"date-time":"2013-04-19T14:08:55Z","timestamp":1366380535000},"page":"243-246","source":"Crossref","is-referenced-by-count":6,"title":["Infundibular widening mimicking anterior communicating artery aneurysm"],"prefix":"10.3171","volume":"119","author":[{"given":"Jaechan","family":"Park","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-Hun","family":"Kang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-jns122058","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"421","DOI":"10.3171\/jns.1995.83.3.0421","article-title":"Clinical study of enlarged infundibular dilation of the origin of the posterior communicating artery","volume":"83","author":"Endo","year":"1995"},{"key":"b2-jns122058","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"529","DOI":"10.3171\/jns.1970.33.5.0529","article-title":"The clinical significance of junctional dilatation of the posterior communicating artery","volume":"33","author":"Epstein","year":"1970"},{"key":"b3-jns122058","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"8","DOI":"10.1016\/j.surneu.2008.01.056","article-title":"Microneurosurgical management of anterior communicating artery aneurysms","volume":"70","author":"Hernesniemi","year":"2008"},{"key":"b4-jns122058","series-title":"Neurosurgery","first-page":"1075","article-title":"Subarachnoid hemorrhage due to rupture of infundibular dilation of a circumflex branch of the posterior cerebral artery: case report","volume":"34","author":"Koike","year":"1994"},{"key":"b5-jns122058","series-title":"Neurol Med Chir (Tokyo)","doi-asserted-by":"publisher","first-page":"25","DOI":"10.2176\/nmc.41.25","article-title":"Successful treatment of a ruptured enlarged infundibular widening of the posterior communicating artery\u2014case report","volume":"41","author":"Kuwahara","year":"2001"},{"key":"b6-jns122058","series-title":"Practical Neuroangiography","first-page":"338","author":"Morris","year":"2007"},{"key":"b7-jns122058","series-title":"Diagnostic Cerebral Angiography","first-page":"272","author":"Osborn","year":"1999"},{"key":"b8-jns122058","series-title":"Radiology","doi-asserted-by":"publisher","first-page":"532","DOI":"10.1148\/radiol.2442060394","article-title":"Intracranial aneurysms: role of multidetector CT angiography in diagnosis and endovascular therapy planning","volume":"244","author":"Papke","year":"2007"},{"key":"b9-jns122058","series-title":"Acta Radiol","doi-asserted-by":"publisher","first-page":"415","DOI":"10.3109\/00016925909171114","article-title":"Infundibular widening of the posterior communicating artery studied by carotid angiography","volume":"51","author":"Saltzman","year":"1959"},{"key":"b10-jns122058","series-title":"AJNR Am J Neuroradiol","first-page":"368","article-title":"Development of aneurysm from infundibulum of posterior communicating artery with documentation of prior hemorrhage","volume":"2","author":"Trasi","year":"1981"},{"key":"b11-jns122058","series-title":"Radiology of the Skull and Brain","first-page":"1171","article-title":"The circle of Willis","volume":"2","author":"Wollschlaeger","year":"1974"}],"container-title":["Journal of Neurosurgery"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg\/119\/1\/article-p243.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/j-neurosurg\/119\/1\/article-p243.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/j-neurosurg\/119\/1\/article-p243.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,8,14]],"date-time":"2022-08-14T17:21:37Z","timestamp":1660497697000},"score":1,"resource":{"primary":{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg\/119\/1\/article-p243.xml"}},"subtitle":["Report of 2 cases"],"short-title":[],"issued":{"date-parts":[[2013,7]]},"references-count":11,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.3171\/2013.3.jns122058","relation":{},"ISSN":["0022-3085","1933-0693"],"issn-type":[{"value":"0022-3085","type":"print"},{"value":"1933-0693","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,7]]}}}
