A third nerve palsy is most often associated with posterior communicating artery aneurysms which are explained by the anatomic proximity of nerve and artery. Third nerve palsies from remote aneurysms however are more difficult to understand.<\/jats:p><\/jats:sec><jats:sec><jats:title>Presentation<\/jats:title><jats:p>A patient presented to the emergency department with severe headache, dizziness, nausea and vomiting. Her examination was remarkable only for a partial left third nerve palsy manifest as a non-pupil sparing mild ptosis. A CT scan and digital subtraction cerebral angiography revealed subarachnoid hemorrhage secondary to a small ruptured aneurysm at the A2 segment of the anterior cerebral artery. The aneurysm was deemed treatable by endovascular coil embolization and the patient underwent successful placement of a detachable helical coil. At 1\u2005month follow-up, the patient had no complaints and showed complete resolution of all oculomotor symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>While oculomotor nerve palsy is an incredibly rare sequelae of anterior cerebral artery aneurysm rupture, it is important that clinicians and researchers continue to report and study such cases. It has been hypothesized that mass effect, hemotoxicity and ischemia are all possible causes of third nerve injury in remote aneurysms, as in this case.<\/jats:p><\/jats:sec>","DOI":"10.1136\/jnis.2010.002964","type":"journal-article","created":{"date-parts":[[2010,10,19]],"date-time":"2010-10-19T02:30:39Z","timestamp":1287455439000},"page":"74-76","source":"Crossref","is-referenced-by-count":7,"title":["Oculomotor nerve palsy in the setting of an anterior cerebral A2 segment aneurysm"],"prefix":"10.1136","volume":"3","author":[{"given":"Carson","family":"Fairbanks","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J Bradley","family":"White","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2010,10,18]]},"reference":[{"key":"2024052222505862000_3.1.74.1","doi-asserted-by":"crossref","first-page":"484","DOI":"10.2176\/nmc.43.484","article-title":"Unilateral oculomotor nerve paresis associated with anterior communicating artery aneurysm rupture","volume":"43","author":"Aiba","year":"2003","journal-title":"Neurol Med Chir"},{"key":"2024052222505862000_3.1.74.2","doi-asserted-by":"crossref","first-page":"257","DOI":"10.1055\/s-2007-979681","article-title":"Third nerve palsies","volume":"27","author":"Bruce","year":"2007","journal-title":"Semin Neurol"},{"key":"2024052222505862000_3.1.74.3","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410140622"},{"key":"2024052222505862000_3.1.74.4","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410130207"},{"key":"2024052222505862000_3.1.74.5","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1007\/s12028-007-0054-4","article-title":"Isolated third nerve palsy associated with a ruptured anterior communicating artery aneurysm","volume":"7","author":"White","year":"2007","journal-title":"Neurocrit Care"},{"key":"2024052222505862000_3.1.74.6","doi-asserted-by":"publisher","DOI":"10.1016\/0090-3019(95)00432-7"},{"key":"2024052222505862000_3.1.74.7","first-page":"181","article-title":"Consecutive oculomotor nerve palsy from a de novo cerebral aneurysm","volume":"13","author":"Striph","year":"1993","journal-title":"J Clin Neuroophthalmol"},{"key":"2024052222505862000_3.1.74.8","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2003.4.3.141"},{"key":"2024052222505862000_3.1.74.9","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199810000-00139"}],"container-title":["Journal of NeuroInterventional Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/jnis.2010.002964","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T06:43:51Z","timestamp":1716446631000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnis.bmj.com\/lookup\/doi\/10.1136\/jnis.2010.002964"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,10,18]]},"references-count":9,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2011,2,9]]},"published-print":{"date-parts":[[2011,3]]}},"alternative-id":["10.1136\/jnis.2010.002964"],"URL":"https:\/\/doi.org\/10.1136\/jnis.2010.002964","relation":{},"ISSN":["1759-8478","1759-8486"],"issn-type":[{"value":"1759-8478","type":"print"},{"value":"1759-8486","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,10,18]]}}}
