Treatment options include observation, radiation therapy and surgical resection. Cerebrospinal fluid (CSF) fistula is a known postsurgical complication that can lead to CSF otorrhoea, rhinorrhoea or CSF leakage from the surgical wound. We present a case report of a patient who underwent vestibular schwannoma resection and postoperatively developed CSF rhinorrhoea, which was refractory to multiple attempts at surgical repair. This was successfully treated under endoscopic and fluoroscopic guidance using a biliary cytology brush to disrupt the surface of the eustachian tube followed by injection of n-Butyl cyanoacrylate.<\/jats:p>","DOI":"10.1136\/bcr-2021-241861","type":"journal-article","created":{"date-parts":[[2021,8,10]],"date-time":"2021-08-10T13:20:20Z","timestamp":1628601620000},"page":"e241861","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic and fluoroscopic-guided closure of the eustachian tube using a biliary cytology brush and liquid embolic agent for a persistent CSF leak after schwannoma resection"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2944-740X","authenticated-orcid":false,"given":"Sharika","family":"Bamezai","sequence":"first","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5854-5041","authenticated-orcid":false,"given":"Zachary M","family":"Wilseck","sequence":"additional","affiliation":[{"name":"Radiology, University of Michigan Hospital, Ann Arbor, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily","family":"Stucken","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Michigan Michigan Medicine, Ann Arbor, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph J","family":"Gemmete","sequence":"additional","affiliation":[{"name":"Radiology, University of Michigan Michigan Medicine, Ann Arbor, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,8,10]]},"reference":[{"key":"2025082709572298000_14.8.e241861.1","doi-asserted-by":"crossref","DOI":"10.1001\/archsurg.1944.01230020080001","article-title":"Treatment of rhinorrhea and otorrhea","volume":"49","author":"Dandy","year":"1944","journal-title":"Arch Surg"},{"key":"2025082709572298000_14.8.e241861.2","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200203000-00020"},{"key":"2025082709572298000_14.8.e241861.3","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e318232e4a4"},{"key":"2025082709572298000_14.8.e241861.4","doi-asserted-by":"crossref","first-page":"473","DOI":"10.1097\/MAO.0b013e3181cdd8fc","article-title":"Prevention of cerebrospinal fluid leak after translabyrinthine resection of vestibular schwannoma","volume":"31","author":"Goddard","year":"2010","journal-title":"Otol Neurotol"},{"key":"2025082709572298000_14.8.e241861.5","article-title":"Endoscopic closure of the eustachian tube for repair of cerebrospinal fluid leak","volume":"17","author":"Kwartler","year":"1996","journal-title":"Am J Otol"},{"key":"2025082709572298000_14.8.e241861.6","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1055\/s-0038-1625975","article-title":"Fluoroscopy-Assisted transnasal Onyx occlusion of the eustachian tube for lateral skull base cerebrospinal fluid leak repair","volume":"79","author":"Patel","year":"2018","journal-title":"J Neurol Surg B Skull Base"},{"key":"2025082709572298000_14.8.e241861.7","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1016\/j.jvir.2014.09.009","article-title":"Interventional radiologic management and treatment of enterocutaneous fistulae","volume":"26","author":"Rahman","year":"2015","journal-title":"J Vasc Interv Radiol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-241861","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T16:57:26Z","timestamp":1756313846000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-241861"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8]]},"references-count":7,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2021,8,10]]},"published-print":{"date-parts":[[2021,8]]}},"alternative-id":["10.1136\/bcr-2021-241861"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-241861","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2021,8]]}}}
