The pain radiated to the right L4\u2013L5 dermatomes. Neurogenic intermittent claudication was &lt;300 m. Motor function was normal. Lumbar magnetic resonance imaging showed a lateral recess stenosis at the L3\u2013L4 and L4\u2013L5 levels. These lesions were operated on by the UBE decompression technique.<\/jats:p><jats:p>No major complications were encountered during the operation. But soon we found out that there was an undiscovered dura tear. We placed the patient under close observation for 2 weeks. After 30 days, we confirmed that subdural hygroma had changed to chronic subdural hematoma. Conservative treatment was continued. On postoperative day 90), the condition was stable and the symptoms improved completely.<\/jats:p><jats:p>\n          Conclusions\u2003We concluded that a spinal cerebrospinal fluid leakage can result in an intracranial subdural hygroma. Intracranial subdural hygromas and hematomas after lumbar spinal surgery should be cautiously assessed and treated.<\/jats:p>","DOI":"10.1055\/s-0041-1723812","type":"journal-article","created":{"date-parts":[[2021,7,14]],"date-time":"2021-07-14T23:24:22Z","timestamp":1626305062000},"page":"502-506","source":"Crossref","is-referenced-by-count":5,"title":["The Transformation of Intracranial Subdural Hygroma to Chronic Subdural Hematoma Following Endoscopic Spinal Surgery: A Case Report"],"prefix":"10.1055","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9828-2768","authenticated-orcid":false,"given":"Guang-Xun","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The First Affiliated Hospital of Xiamen University, Xiamen, PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Min","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, Changhua Christian Hospital, Changhua, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5086-0875","authenticated-orcid":false,"given":"Jin-Sung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Seoul St. Mary\u2019s Hospital, The Catholic University of Korea, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwan-Su","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Him Plus Hospital, Suncheon, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,7,14]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"58","DOI":"10.1007\/s00586-010-1493-8","article-title":"Dural tears in percutaneous endoscopic lumbar discectomy","volume":"20","author":"Y Ahn","year":"2011","journal-title":"Eur Spine J"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"494","DOI":"10.1016\/j.wneu.2018.05.251","article-title":"Management of dural tears in endoscopic lumbar spinal surgery: a review of the literature","volume":"119","author":"S J M\u00fcller","year":"2018","journal-title":"World Neurosurg"},{"issue":"24","key":"ref3","doi-asserted-by":"crossref","first-page":"E730","DOI":"10.1097\/01.brs.0000192208.66360.29","article-title":"Acute intracranial subdural hematoma following a lumbar CSF leak caused by spine surgery","volume":"30","author":"D M Sciubba","year":"2005","journal-title":"Spine"},{"issue":"19","key":"ref4","doi-asserted-by":"crossref","first-page":"2286","DOI":"10.1001\/jama.295.19.2286","article-title":"Spontaneous spinal cerebrospinal fluid leaks and intracranial hypotension","volume":"295","author":"W I Schievink","year":"2006","journal-title":"JAMA"},{"issue":"06","key":"ref5","first-page":"1361","article-title":"Cerebellar hemorrhage after spinal surgery: report of two cases and literature review","volume":"50","author":"J A Friedman","year":"2002","journal-title":"Neurosurgery"},{"issue":"01","key":"ref6","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1007\/s00586-005-0987-2","article-title":"Cerebellar hemorrhage after spinal surgery: case report and review of the literature","volume":"15","author":"D Konya","year":"2006","journal-title":"Eur Spine J"},{"issue":"12","key":"ref7","doi-asserted-by":"crossref","first-page":"E743","DOI":"10.1097\/BRS.0000000000000323","article-title":"Supratentorial subdural hemorrhage of a previous head injury and cerebellar hemorrhage after cervical spinal surgery: a case report and review of the literature","volume":"39","author":"T Morimoto","year":"2014","journal-title":"Spine"},{"issue":"01","key":"ref8","doi-asserted-by":"crossref","first-page":"E277","DOI":"10.1227\/NEU.0b013e3181fead14","article-title":"Pseudohypoxic brain swelling (postoperative intracranial hypotension-associated venous congestion) after spinal surgery: report of 2 cases","volume":"68","author":"Y Parpaley","year":"2011","journal-title":"Neurosurgery"},{"issue":"02","key":"ref9","doi-asserted-by":"crossref","first-page":"144","DOI":"10.1111\/j.1365-2044.1983.tb13934.x","article-title":"Subdural haematoma and spinal anaesthesia.
