However, vestibular schwannoma has a known association with communicating hydrocephalus presenting with symptoms of normal pressure hydrocephalus and requiring treatment by ventricular shunting or tumour resection. We report a 79-year-old woman who presented with subacute gait apraxia, cognitive impairment and urinary incontinence. CT and MR imaging identified a 20\u2009mm vestibular schwannoma and communicating hydrocephalus; her cerebrospinal fluid (CSF) protein was elevated. Her symptoms improved following ventriculoperitoneal shunt insertion. The mechanism by which non-obstructing vestibular schwannoma causes hydrocephalus is unclear, but hyperproteinorrachia is probably important, likely by impeding CSF resorption.<\/jats:p>","DOI":"10.1136\/pn-2024-004240","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T13:44:54Z","timestamp":1724334294000},"page":"70-74","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Vestibular schwannoma causing normal pressure hydrocephalus"],"prefix":"10.1136","volume":"25","author":[{"given":"Alexander","family":"Hayes","sequence":"first","affiliation":[{"name":"Imperial College London, Department of Brain Sciences, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Wilson","sequence":"additional","affiliation":[{"name":"Neurosurgery, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastassia","family":"Gontsarova","sequence":"additional","affiliation":[{"name":"Radiology, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Carswell","sequence":"additional","affiliation":[{"name":"Imperial College London, Department of Brain Sciences, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2024,8,22]]},"reference":[{"key":"2025090410434363000_25.1.70.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-200106000-00010"},{"key":"2025090410434363000_25.1.70.2","doi-asserted-by":"publisher","DOI":"10.1136\/pn-2021-003291"},{"key":"2025090410434363000_25.1.70.3","doi-asserted-by":"publisher","DOI":"10.1111\/ene.13555"},{"key":"2025090410434363000_25.1.70.4","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1007\/s00701-002-1021-7","article-title":"Non-obstructive hydrocephalus associated with intracranial schwannomas: hyperproteinorrhachia as an etiopathological factor?","volume":"145","author":"Bloch","year":"2003","journal-title":"Acta Neurochir (Wien)"},{"key":"2025090410434363000_25.1.70.5","doi-asserted-by":"publisher","DOI":"10.1227\/01.neu.0000306096.61012.22"},{"key":"2025090410434363000_25.1.70.6","doi-asserted-by":"publisher","DOI":"10.1159\/000111149"},{"key":"2025090410434363000_25.1.70.7","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/j.medcli.2019.05.021","article-title":"Vestibular schwannoma and normal pressure hydrocephalus: An infrequent association as a cause of dementia","volume":"154","author":"Felices-Farias","year":"2020","journal-title":"Med Clin (Barc)"},{"key":"2025090410434363000_25.1.70.8","doi-asserted-by":"crossref","first-page":"585","DOI":"10.4103\/0028-3886.378645","article-title":"Normal Pressure Hydrocephalus Associated with Small Vestibular Schwannomas: To Treat the Cause or its Effect?","volume":"71","author":"Kumar","year":"2023","journal-title":"Neurol India"},{"key":"2025090410434363000_25.1.70.9","doi-asserted-by":"crossref","first-page":"1188","DOI":"10.3171\/jns.2003.98.6.1188","article-title":"Clinical and neuroimaging characteristics of hydrocephalus associated with vestibular schwannoma","volume":"98","author":"Tanaka","year":"2003","journal-title":"J Neurosurg"},{"key":"2025090410434363000_25.1.70.10","article-title":"Hydrocephalus After Gamma Knife Radiosurgery for Vestibular Schwannoma: favorable Outcomes After Shunt Placement","volume":"14","author":"Marshalik","year":"2022","journal-title":"Cureus"},{"key":"2025090410434363000_25.1.70.11","doi-asserted-by":"publisher","DOI":"10.1080\/02688699550040927"},{"key":"2025090410434363000_25.1.70.12","doi-asserted-by":"publisher","DOI":"10.1055\/s-0033-1333621"}],"container-title":["Practical Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/pn-2024-004240","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T17:43:54Z","timestamp":1757007834000},"score":1,"resource":{"primary":{"URL":"https:\/\/pn.bmj.com\/lookup\/doi\/10.1136\/pn-2024-004240"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,22]]},"references-count":12,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,1,16]]},"published-print":{"date-parts":[[2025,2]]}},"alternative-id":["10.1136\/pn-2024-004240"],"URL":"https:\/\/doi.org\/10.1136\/pn-2024-004240","relation":{},"ISSN":["1474-7758","1474-7766"],"issn-type":[{"value":"1474-7758","type":"print"},{"value":"1474-7766","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,8,22]]}}}
