The arachnoid granulations or villi are concentrated along with the dural venous sinuses in the cerebral convexity, parasagittally, and sphenoid wing regions. The majority of meningiomas are found in these locations with dural attachment. Infrequently, meningiomas develop without dural attachment but in dural adjacent. There are numerous reports of patients with cranial nerve involvement as a result of the compressive effect of the sinus cavernous or adjacent structures meningioma tumor on the cranial nerve.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nIn this study, we reviewed all reports of patients with third nerve involvement as a result of meningioma tumors in addition to the introduction of a new case. We present a 47-year-old woman presented with headache, diplopia, and ptosis. A gadolinium-enhanced mass on anterolateral of the left cerebral peduncle with no dural attachment was suggesting for Schwannoma at preoperative imaging. An adhesive 10 \u00d7 5 \u00d7 4 mm meningothelial meningioma arising from the oculomotor nerve was resected.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nThe findings of this review suggest that there may be other mechanisms as the origin of meningiomas tumors. It is crucial to take into account origination mechanisms of meningioma using ectopic meningiomas due to the increasing prevalence of meningioma.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_312_2020","type":"journal-article","created":{"date-parts":[[2020,10,2]],"date-time":"2020-10-02T06:50:19Z","timestamp":1601621419000},"page":"314","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Meningothelial meningioma of the oculomotor nerve: A case report and review of the literature"],"prefix":"10.25259","volume":"11","author":[{"given":"Guive","family":"Sharifi","sequence":"first","affiliation":[{"name":"Skull Base Research Center, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmoud","family":"Lotfinia","sequence":"additional","affiliation":[{"name":"Medius Klinik Kirchheim, University of T\u00fcbingen, Kirchheim, Germany,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmoud","family":"Omidbeigi","sequence":"additional","affiliation":[{"name":"Skull Base Research Center, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sina","family":"Asaadi","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Neurosurgery, Firoozgar Hospital, Iran University of Medical Sciences, Tehran, Iran."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farahnaz Bidari","family":"Zerehpoosh","sequence":"additional","affiliation":[{"name":"Skull Base Research Center, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2020,10,2]]},"reference":[{"key":"10.25259\/SNI_312_2020\/ref-1","doi-asserted-by":"crossref","first-page":"1087","DOI":"10.1148\/radiographics.11.6.1749851","article-title":"Typical, atypical, and misleading features in meningioma","volume":"11","author":"Buetow","year":"1991","journal-title":"Radiographics"},{"key":"10.25259\/SNI_312_2020\/ref-2","doi-asserted-by":"crossref","first-page":"259","DOI":"10.3171\/2011.3.JNS101748","article-title":"Treatment and survival of patients with nonmalignant intracranial meningioma: Results from the Surveillance, Epidemiology, and end results program of the national cancer institute.
