Magnetic resonance imaging showed an epidural mass linked to the ligamentum flavum. The mass was isointense in T1-weighted images, and was centrally hyperintense and peripherally hypointense in T2-weighted images. Surgical removal of the ligamentum flavum achieved resolution of the symptoms. The definitive diagnosis could only be confirmed by histopathological examinations. The differential diagnoses include lumbar disc herniation and lumbar spinal canal stenosis caused by neoplasm, infection, epidural haematoma, or facet cyst.<\/jats:p>","DOI":"10.1177\/230949900901700219","type":"journal-article","created":{"date-parts":[[2016,10,4]],"date-time":"2016-10-04T17:14:58Z","timestamp":1475601298000},"page":"212-215","source":"Crossref","is-referenced-by-count":12,"title":["Ligamentum Flavum Haematoma: A Report of Two Cases"],"prefix":"10.1177","volume":"17","author":[{"given":"Hiroshi","family":"Takahashi","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihito","family":"Wada","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichirou","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinichirou","family":"Fukushi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuro","family":"Sakurai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazutoshi","family":"Shibuya","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Suguro","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Toho University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,8,1]]},"reference":[{"key":"bibr1-230949900901700219","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1992.76.3.0534"},{"key":"bibr2-230949900901700219","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199507000-00012"},{"key":"bibr3-230949900901700219","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200005010-00021"},{"key":"bibr4-230949900901700219","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-3019(00)00187-7"},{"key":"bibr5-230949900901700219","first-page":"101","volume":"34","author":"Inoue T","year":"2003","journal-title":"Kanto Seikeisaigaigeka Gakkai Zasshi"},{"key":"bibr6-230949900901700219","first-page":"879","volume":"37","author":"Kumazawa S","year":"2002","journal-title":"Rinsho Seikei Geka"},{"key":"bibr7-230949900901700219","first-page":"1485","volume":"48","author":"Takeda M","year":"2005","journal-title":"Orthop Surg Traumatol"},{"key":"bibr8-230949900901700219","first-page":"223","volume":"20","author":"Hashimoto H","year":"2008","journal-title":"J East Jpn Orthop Traumatol"}],"container-title":["Journal of Orthopaedic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/230949900901700219","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/230949900901700219","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T00:15:40Z","timestamp":1777594540000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/230949900901700219"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8]]},"references-count":8,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2009,8]]}},"alternative-id":["10.1177\/230949900901700219"],"URL":"https:\/\/doi.org\/10.1177\/230949900901700219","relation":{},"ISSN":["1022-5536","2309-4990"],"issn-type":[{"value":"1022-5536","type":"print"},{"value":"2309-4990","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8]]}}}
