Spontaneous resolution without intervention is rare, and its underlying mechanism has not been established.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n A 33-year-old female developed a SIH following chiropractic manipulation. The magnetic resonance imaging (MRI) demonstrated a ventral CSF leak at the Th2\/3 level. During conservative management, she experienced acute back pain coinciding with the formation of an epidural hematoma at the same level; her headache resolved promptly thereafter. Serial MRI scans showed gradual resorption of the hematoma without her incurring any new neurological deficit. Later, computed tomography myelography confirmed cessation of CSF leakage despite a persistent dural defect due to the spontaneous epidural hematoma.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n In a 33-year-old female, a spontaneous T2\/3 epidural hematoma resulted in an endogenous blood patch that mechanically occluded a dural tear, causing SIH.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_385_2026","type":"journal-article","created":{"date-parts":[[2026,5,29]],"date-time":"2026-05-29T11:19:52Z","timestamp":1780053592000},"page":"323","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spontaneous epidural blood patch at T2\/3 with resolution of intracranial hypotension"],"prefix":"10.25259","volume":"17","author":[{"given":"Keita","family":"Hashimoto","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurika","family":"Terasawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rento","family":"Miyazaki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michihisa","family":"Narikiyo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"So","family":"Ohashi","sequence":"additional","affiliation":[{"name":"Tokyo Spine Joint Clinic Haneda, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirokazu","family":"Nagasaki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshifumi","family":"Tsuboi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidenori","family":"Matsuoka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kawasaki Saiwai Hospital, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2026,5,29]]},"reference":[{"key":"10.25259\/SNI_385_2026\/ref-1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1001\/jamaneurol.2020.4799","article-title":"Clinical presentation, investigation findings, and treatment outcomes of spontaneous intracranial hypotension syndrome","volume":"78","author":"D\u2019Antona","year":"2021","journal-title":"JAMA Neurol"},{"key":"10.25259\/SNI_385_2026\/ref-2","first-page":"745","article-title":"Spontaneous intracranial hypotension: A systematic imaging approach for CSF leak localization and management based on MRI and digital subtraction myelography","volume":"40","author":"Farb","year":"2019","journal-title":"AJNR Am J Neuroradiol"},{"key":"10.25259\/SNI_385_2026\/ref-3","doi-asserted-by":"crossref","first-page":"CASE21615","DOI":"10.3171\/CASE21615","article-title":"Intracranial hypotension due to ventral thoracic dural tear secondary to osteophyte complex: Resolution after transdural thoracic microdiscectomy with dural repair.
