Ectopic origin of an ONB is exceedingly rare. We describe a rare case of an ectopic sphenoclival ONB with extensive involvement of the central skull base and with development of systemic metastases. To our knowledge, ours is the first case that describes the imaging features of this rare entity on computed tomography (CT), magnetic resonance imaging, 18 F\u2010fluorodeoxyglucose\u2013positron\u2010emission tomography\/CT, and digital subtraction angiography. We also describe the histological features, imaging differentials, and treatment options for this tumor along with a brief literature review. <jats:italic>Laryngoscope<\/jats:italic>, 125:822\u2013825, 2015<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.24925","type":"journal-article","created":{"date-parts":[[2014,9,12]],"date-time":"2014-09-12T13:48:55Z","timestamp":1410529735000},"page":"822-825","source":"Crossref","is-referenced-by-count":13,"title":["Aggressive primary olfactory neuroblastoma of the sphenoclival region: A case report and literature review"],"prefix":"10.1002","volume":"125","author":[{"given":"Bela","family":"Purohit","sequence":"first","affiliation":[{"name":"Institute for Neuroradiology, University Hospital of Zurich Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Winder","sequence":"additional","affiliation":[{"name":"Clinic for Oncology, University Hospital of Zurich Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewerton M.","family":"Maggio","sequence":"additional","affiliation":[{"name":"Institute for Surgical Pathology, University Hospital of Zurich Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Spyros S.","family":"Kollias","sequence":"additional","affiliation":[{"name":"Institute for Neuroradiology, University Hospital of Zurich Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,9,12]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-009-0125-2"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-010-1423-8"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/02688699845113"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/ajot.2001.26500"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0899-7071(02)00533-8"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2004.03.002"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1607-551X(09)70046-4"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.4103\/2231-0770.94806"},{"key":"e_1_2_5_10_1","first-page":"240","volume-title":"Tumors of the Upper Respiratory Tract and Ear","author":"Hyams VJ","year":"1988"},{"key":"e_1_2_5_11_1","doi-asserted-by":"crossref","first-page":"843","DOI":"10.1288\/00005537-199208000-00001","article-title":"Esthesioneuroblastoma: the UCLA experience 1970\u20131990","volume":"102","author":"Dulgerov P","year":"1992","journal-title":"Laryngoscope"}],"container-title":["The Laryngoscope"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Flary.24925","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/lary.24925","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,4]],"date-time":"2023-10-04T06:42:51Z","timestamp":1696401771000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/lary.24925"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9,12]]},"references-count":10,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2015,4]]}},"alternative-id":["10.1002\/lary.24925"],"URL":"https:\/\/doi.org\/10.1002\/lary.24925","archive":["Portico"],"relation":{},"ISSN":["0023-852X","1531-4995"],"issn-type":[{"value":"0023-852X","type":"print"},{"value":"1531-4995","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,9,12]]}}}
