This retrospective study was approved by the institutional review board. Patients diagnosed with nontraumatic intracranial SDH who underwent computed tomography (CT) myelography between January 2012 and March 2018 were selected. 60 patients (male: female, 39:21; age range, 20\u201382 years) were enrolled and divided into CSF leak-positive and CSF leak-negative groups according to CT myelography data. Clinical findings were statistically compared between the two groups. Spinal CSF leak was observed in 80% (48\/60) of patients, and it was significantly associated with an age of &lt;69 years (p = 0.006). However, patients aged \u226569 years also had a tendency to exhibit spontaneous intracranial hypotension (SIH)-induced nontraumatic intracranial SDH (60.87%; 14\/23). Therefore, CT myelography is recommended to be performed for the evaluation of possible SIH in patients with nontraumatic intracranial SDH, particularly those aged &lt;69 years. Patients aged \u226569 years are also good candidates for CT myelography because SIH tends to occur even in this age group.<\/jats:p>","DOI":"10.3390\/diagnostics11122278","type":"journal-article","created":{"date-parts":[[2021,12,6]],"date-time":"2021-12-06T22:18:42Z","timestamp":1638829122000},"page":"2278","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Incidence of Spinal CSF Leakage on CT Myelography in Patients with Nontraumatic Intracranial Subdural Hematoma"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0549-5722","authenticated-orcid":false,"given":"Hyo Jin","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Radiology, Seoul National University Bundang Hospital, 82 Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam 13620, Korea"},{"name":"Department of Radiology, Seoul Metropolitan Government-Seoul National University Boramae Medical Center, Seoul National University College of Medicine, 20 Boramae-ro 5-gil, Dongjak-gu, Seoul 07061, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7106-5229","authenticated-orcid":false,"given":"Joon Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Bundang Hospital, 82 Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam 13620, Korea"},{"name":"Department of Radiology, Seoul National University College of Medicine, Seoul 03080, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4205-2362","authenticated-orcid":false,"given":"Eugene","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Bundang Hospital, 82 Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam 13620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuhn","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Bundang Hospital, 82 Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam 13620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joong Mo","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Bundang Hospital, 82 Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam 13620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1097\/00000433-199306000-00005","article-title":"Nontraumatic acute subdural hematoma: A case report and review of the literature","volume":"14","author":"Avis","year":"1993","journal-title":"Am.
