Our aim was to describe a unique case of occlusion of an anterior cerebral artery mimicking a cerebral aneurysm in a probable moyamoya disease patient, and to highlight its clinical presentation, diagnosis, and management, and to perform an extensive literature review.<\/jats:p><jats:p>\n          Case\u2003A 67-year-old man suffering from recurrent dizziness for 3 months. Previous medical history was unremarkable. Brain magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) demonstrated occlusion of the right middle cerebral artery (MCA) associated with a \u201cprobable moyamoya disease\u201d and an aneurysm-like shadow protruding lesion at the anterior communicating artery (AcomA). Perfusion images showed ischemia along the right temporo-occipital lobe. Due to MCA occlusion with perfusion deficits and unspecific symptoms, we offered a right side encephalo-duro-myo-synangiosis (EDMS) and clipping of the AcomA aneurysm in one session. Intraoperatively, there was no evidence of the AcomA aneurysm; instead, this finding corresponded to the stump of the occluded right anterior cerebral artery (A1 segment). This segment appeared to be of yellowish color due to atherosclerosis and lacked blood flow. The patient underwent as previously planned a right side EDMS and the perioperative course was uneventful without the presence of additional ischemic attacks.<\/jats:p><jats:p>\n          Conclusion\u2003Arterial branch occlusions can sometimes present atypical angiographic characteristics that can mimic a saccular intracranial aneurysm. It is relevant to consider this radiographic differential diagnosis, especially when aneurysm treatment is planned.<\/jats:p>","DOI":"10.1055\/s-0040-1722272","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T22:47:21Z","timestamp":1621896441000},"page":"606-610","source":"Crossref","is-referenced-by-count":4,"title":["Occlusion of the Anterior Cerebral Artery Mimicking a Cerebral Aneurysm: Clinical Presentation and Literature Review"],"prefix":"10.1055","volume":"83","author":[{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Cerebrovascular Disease Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaochao","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tianjin Medical University General Hospital, Key Laboratory of Post-Trauma Neuro-Repair and Regeneration in Central Nervous System, Ministry of Education and Tianjin City; Tianjin Key Laboratory of Injuries, Variations and Regeneration of Nervous System, Tianjin, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhu","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Pathology, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liming","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Cerebrovascular Disease Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juha","family":"Hernesniemi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Cerebrovascular Disease Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaoyue","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Cerebrovascular Disease Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6673-6369","authenticated-orcid":false,"given":"Hugo","family":"Andrade-Barazarte","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Zhengzhou University People\u2019s Hospital, Henan Provincial People\u2019s Hospital, Cerebrovascular Disease Hospital, Henan University People\u2019s Hospital, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,5,24]]},"reference":[{"issue":"10","key":"ref1","doi-asserted-by":"crossref","first-page":"1598","DOI":"10.1016\/j.ejrad.2012.12.026","article-title":"Epidemiology and genetics of intracranial aneurysms","volume":"82","author":"F Caranci","year":"2013","journal-title":"Eur J Radiol"},{"issue":"05","key":"ref2","doi-asserted-by":"crossref","first-page":"1052","DOI":"10.3171\/JNS\/2008\/108\/5\/1052","article-title":"Natural history of unruptured intracranial aneurysms: probability of and risk factors for aneurysm rupture","volume":"108","author":"S Juvela","year":"2008","journal-title":"J Neurosurg"},{"issue":"05","key":"ref3","first-page":"249","article-title":"Unruptured cerebral aneurysms.
