Data collected included demographics, nature of presentation, imaging findings, intraoperative location of skull\u2010base defect, and clinical follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Forty\u2010six patients' charts were reviewed. Among these patients, 15 did not show a bony skull\u2010base defect on high\u2010resolution computed tomography (CT) scan. They did, however, each show a small area of opacification in the olfactory cleft. In each case, this area of opacification correlated with the site of the CSF leak. Intrathecal fluorescein was not used, except in 2 instances. Successful repair was noted in all patients on follow\u2010up, without evidence of recurrence at the repair site.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>In the absence of a clearly identifiable bony skull\u2010base defect, opacification of the olfactory cleft is a localizing sign in some cases of spontaneous CSF rhinorrhea. Such a finding should direct endoscopic repair, and may serve as the only marker for the specific leak site. \u00a92012 ARSAAOA, LLC.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21048","type":"journal-article","created":{"date-parts":[[2012,5,7]],"date-time":"2012-05-07T16:57:37Z","timestamp":1336409857000},"page":"402-404","source":"Crossref","is-referenced-by-count":18,"title":["A novel finding on computed tomography in the diagnosis and localization of cerebrospinal fluid leaks without a clear bony defect"],"prefix":"10.1002","volume":"2","author":[{"given":"R.","family":"Peter Manes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew W.","family":"Ryan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bradley F.","family":"Marple","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,5,7]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/194589240301700403"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348940611500703"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A0840"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.2500\/ajr.2008.22.3150"}],"container-title":["International Forum of Allergy &amp; Rhinology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21048","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/alr.21048","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T17:53:48Z","timestamp":1698774828000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/alr.21048"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,5,7]]},"references-count":4,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2012,9]]}},"alternative-id":["10.1002\/alr.21048"],"URL":"https:\/\/doi.org\/10.1002\/alr.21048","archive":["Portico"],"relation":{},"ISSN":["2042-6976","2042-6984"],"issn-type":[{"value":"2042-6976","type":"print"},{"value":"2042-6984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,5,7]]}}}
