The most common histopathological subtype is meningeal epithelioma. In clinical practice, primary heterotopic nasal meningioma occurs relatively rarely, and its most common pathological type is psammomatous meningioma, whereas nasal fibrous meningioma is infrequent. In our case, a 31-year-old male patient was admitted to the hospital with \u201cprogressive nasal obstruction on the right side for half a year.\u201d Computed tomography examination of the paranasal sinuses revealed a polyploid mass in the right nasal cavity. The patient underwent surgical resection of the mass under nasal endoscopy. Histopathological examination confirmed that the mass was an ectopic meningioma of the nasal cavity. The patient was regularly followed up for 2 years without recurrence of the tumor. Primary heterotopic fibrous meningioma of the nasal cavity is clinically rare but should be considered as a differential diagnosis for hemangioma of the nasal cavity, inverted papilloma, and nasal polyp. The final diagnosis is based on pathology and immunohistochemistry analysis results.<\/jats:p>","DOI":"10.1177\/0145561320974863","type":"journal-article","created":{"date-parts":[[2020,11,20]],"date-time":"2020-11-20T07:49:48Z","timestamp":1605858588000},"page":"NP383-NP388","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Primary Heterotopic Meningioma of Nasal Cavity: Case Report and Literature Review"],"prefix":"10.1177","volume":"101","author":[{"given":"Xianwen","family":"Hu","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"},{"name":"Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maoyan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zelong","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pathology, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7251-2329","authenticated-orcid":false,"given":"Jiong","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, Guizhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,11,20]]},"reference":[{"issue":"4","key":"bibr1-0145561320974863","first-page":"412","volume":"4","author":"Lia ZD","year":"2005","journal-title":"Chinese J Neurology"},{"key":"bibr2-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcms.2011.06.003"},{"key":"bibr3-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1159\/000275463"},{"key":"bibr4-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2407-12-275"},{"issue":"11","key":"bibr5-0145561320974863","first-page":"MD01","volume":"10","author":"Wadhera R","year":"2016","journal-title":"J Clin Diagn Res"},{"key":"bibr6-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1097\/PAI.0b013e3181cc7db9"},{"key":"bibr7-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19800915)46:6<1442::AID-CNCR2820460625>3.0.CO;2-3"},{"key":"bibr8-0145561320974863","first-page":"889","volume":"18","author":"Maharjan L","year":"2018","journal-title":"Case Rep Otolaryngol"},{"key":"bibr9-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2303.1996.35382353.x"},{"key":"bibr10-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19841101)54:9<1860::AID-CNCR2820540916>3.0.CO;2-9"},{"issue":"5","key":"bibr11-0145561320974863","first-page":"5624","volume":"8","author":"Liu Y","year":"2015","journal-title":"Int J Clin Exp Pathol"},{"issue":"8","key":"bibr12-0145561320974863","first-page":"1459","volume":"26","author":"Gao Y","year":"2010","journal-title":"Chinese Med Imaging Technol"},{"issue":"8","key":"bibr13-0145561320974863","first-page":"916","volume":"29","author":"Gao YL","year":"2013","journal-title":"J Clin Exper Pathol"},{"key":"bibr14-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200005000-00002"},{"key":"bibr15-0145561320974863","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2000.93.1.0132"},{"key":"bibr16-0145561320974863","doi-asserted-by":"publisher","DOI":"10.1002\/lary.22495"}],"container-title":["Ear, Nose &amp;
