From these cases, patients with brain MRIs consistent with SIH were also identified. Subsequently, the overall proportion of SLEC-negative SIH was determined as a function of total cases with NRD based on spinal level.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 83,843 patients with spinal MRIs were screened which identified 4174 (4.97%) with NRD. From these, there were 1203 cervical, 622 thoracic, and 2979 lumbosacral spine MRIs. In total, 16 patients (0.38%; Standard Error [SE]: 0.48%\u20130.28%) had a brain MRI compatible with SLEC-negative SIH and met ICHD-3 criteria. Patients with cervical NRD had SIH in 2 cases (0.16%; SE: 0.27%\u20130.05%). SLEC-negative SIH was present in 11 patients with lumbosacral NRD (0.34%; SE: 0.44%\u20130.24%). In patients with diverticula in the thoracic spine, 14 (2.3%; SE: 2.8%\u20131.8%) had SLEC-negative SIH. SLEC-negative SIH was significantly more prevalent in patients with thoracic diverticula compared to those with cervical ( p&lt;.0001) or lumbosacral NRD ( p&lt;.0001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In patients with spinal NRD, concurrent SLEC-negative SIH is present in approximately 0.38% of patients, suggesting that in the vast majority of cases, they are an incidental finding. However, SIH is present in approximately 2.3% of patients with thoracic NRD and may be more specific for leak localization.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19714009231196467","type":"journal-article","created":{"date-parts":[[2023,8,17]],"date-time":"2023-08-17T04:00:08Z","timestamp":1692244808000},"page":"736-739","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Prevalence of SLEC-negative spontaneous intracranial hypotension in patients with spinal nerve root sleeve diverticula on MRI"],"prefix":"10.1177","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3247-0854","authenticated-orcid":false,"given":"Derrek","family":"Schartz","sequence":"first","affiliation":[{"name":"Department of Imaging Sciences, University of Rochester Medical Center, USA"},{"name":"Department of Neurosurgery, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathaniel","family":"Ellens","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rahim","family":"Ismail","sequence":"additional","affiliation":[{"name":"Department of Imaging Sciences, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clifton","family":"Houk","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex","family":"Kessler","sequence":"additional","affiliation":[{"name":"Department of Imaging Sciences, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shehanaz","family":"Ellika","sequence":"additional","affiliation":[{"name":"Department of Imaging Sciences, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew T","family":"Bender","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Rochester Medical Center, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,8,17]]},"reference":[{"key":"bibr1-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-021-02766-z"},{"key":"bibr2-19714009231196467","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A7548"},{"key":"bibr3-19714009231196467","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.17.18351"},{"key":"bibr4-19714009231196467","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A6521"},{"key":"bibr5-19714009231196467","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A3359"},{"key":"bibr6-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(21)00423-3"},{"key":"bibr7-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000002986"},{"key":"bibr8-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1177\/03331024211048510"},{"key":"bibr9-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1177\/15910199231165429"},{"key":"bibr10-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-020-02644-y"},{"key":"bibr11-19714009231196467","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2017.01.123"}],"container-title":["The Neuroradiology Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/19714009231196467","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/19714009231196467","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/19714009231196467","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:38:08Z","timestamp":1777588688000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/19714009231196467"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,8,17]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2023,12]]}},"alternative-id":["10.1177\/19714009231196467"],"URL":"https:\/\/doi.org\/10.1177\/19714009231196467","relation":{},"ISSN":["1971-4009","2385-1996"],"issn-type":[{"value":"1971-4009","type":"print"},{"value":"2385-1996","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,8,17]]}}}
