Here, we report two cases of NPH attributed to cauda equina ependymomas.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 63-year-old male presented with progressive gait disturbance, dementia, and urinary incontinence. When the lumbar MR documented an intradural tumor involving the cauda equina at the L2-L3 level; the tumor was excised; pathologically, it proved to be a myxopapillary ependymoma. Postoperatively, however, the patient\u2019s continued gait disturbance led to a brain CT that documented ventricular dilation consistent with NPH; following ventriculoperitoneal (VP) shunt placement his symptoms improved. A 65-year-old female also presented with gait disturbance, dementia, and urinary retention. Here, procedures were performed in reverse. When a brain CT showed hydrocephalus, a VP shunt was placed. When symptoms persisted, a lumbar MR demonstrated a T12-L2 intradural tumor; following a lumbar laminectomy for tumor excision, symptoms stabilized. The pathological diagnosis was also consistent with a conus\/cauda equina ependymoma. Over the next 10 years, the patient had residual bladder dysfunction (e.g., requiring straight catheterization), but had no shunt dysfunction.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nWe observed two cases of ependymomas of the cauda equina and brain CTs documenting NPH that was successfully surgically managed with stabilization of neurological deficit. In the first case, L2-L3 laminectomy for tumor removal was succeeded by shunting for NPH, while in the second case, initial VP shunting for NPH was followed by a T12-L2 laminectomy for tumor excision.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_851_2020","type":"journal-article","created":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T11:53:41Z","timestamp":1609847621000},"page":"8","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Two cases of normal pressure hydrocephalus caused by ependymoma of the cauda equina"],"prefix":"10.25259","volume":"12","author":[{"given":"Isamu","family":"Miura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Motoo","family":"Kubota","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhiko","family":"Momozaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahito","family":"Yuzurihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2021,1,5]]},"reference":[{"key":"10.25259\/SNI_851_2020\/ref-1","first-page":"206","article-title":"Tumors of the conus medullaris and of the cauda equina associated with chronic hydrocephalus: about 2 cases","volume":"29","author":"Khoulali","year":"2018","journal-title":"Pan Afr Med J"},{"key":"10.25259\/SNI_851_2020\/ref-2","doi-asserted-by":"crossref","first-page":"850","DOI":"10.4065\/75.8.850","article-title":"Recurrent lumbar ependymoma presenting as headache and communicating hydrocephalus","volume":"75","author":"Phan","year":"2000","journal-title":"Mayo Clin Proc"},{"key":"10.25259\/SNI_851_2020\/ref-3","first-page":"338","article-title":"Myxopapillary ependymoma of cauda equina presented with communicating hydrocephalus and papilloedema: A case report","volume":"74","author":"Ting","year":"2019","journal-title":"Med J Malaysia"},{"key":"10.25259\/SNI_851_2020\/ref-4","doi-asserted-by":"crossref","first-page":"399","DOI":"10.1159\/000106390","article-title":"Ependymoma of the cauda equina starting with communicating hydrocephalus: A case report","volume":"43","author":"Tzekov","year":"2007","journal-title":"Pediatr Neurosurg"},{"key":"10.25259\/SNI_851_2020\/ref-5","doi-asserted-by":"crossref","first-page":"423","DOI":"10.2176\/nmc.cr2012-0365","article-title":"Normal pressure hydrocephalus caused by a spinal neurinoma at the cauda equina level: A case report","volume":"54","author":"Wajima","year":"2014","journal-title":"Neurol Med Chir (Tokyo)"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/two-cases-of-normal-pressure-hydrocephalus-caused-by-ependymoma-of-the-cauda-equina\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/two-cases-of-normal-pressure-hydrocephalus-caused-by-ependymoma-of-the-cauda-equina\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T11:53:49Z","timestamp":1609847629000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/two-cases-of-normal-pressure-hydrocephalus-caused-by-ependymoma-of-the-cauda-equina\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,5]]},"references-count":5,"alternative-id":["10.25259\/SNI_851_2020"],"URL":"https:\/\/doi.org\/10.25259\/sni_851_2020","relation":{},"ISSN":["2152-7806"],"issn-type":[{"value":"2152-7806","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,1,5]]},"article-number":"8"}}
