The authors, however, describe a novel case involving a butterfly vertebra overlapping with disc herniation that presented as radiculopathy. A butterfly vertebra is characterized by a symmetrical fusion defect resulting in a sagittal cleft vertebra. Only a few cases of butterfly vertebrae have been reported as incidental findings. This spinal anomaly may be associated with other congenital conditions such as Pfeiffer, Crouzon, Jarcho-Levin, and Alagille syndromes. Moreover, there is no previous report of a case associated with symptomatic disc herniation from the sagittal cleft.<\/jats:p>\n<jats:p>The authors excised the herniated disc fragment. They performed intraoperative discography after exposure of the corresponding intervertebral space via a conventional interlaminar approach. Histological examination of a tissue specimen showed scattered chondrocytes in the myxohyaline stroma, which indicated the nucleus pulposus.<\/jats:p>","DOI":"10.3171\/2011.6.spine1178","type":"journal-article","created":{"date-parts":[[2011,8,5]],"date-time":"2011-08-05T14:06:51Z","timestamp":1312553211000},"page":"567-570","source":"Crossref","is-referenced-by-count":26,"title":["Butterfly vertebra with lumbar intervertebral disc herniation"],"prefix":"10.3171","volume":"15","author":[{"given":"Hyung-Lea","family":"Cho","sequence":"first","affiliation":[{"name":"1Department of Neurosurgery, Dongrae Wooridul Spine Hospital, Busan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin-Sung","family":"Kim","sequence":"additional","affiliation":[{"name":"2Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Suk","family":"Paeng","sequence":"additional","affiliation":[{"name":"3Pathology, Wooridul Spine Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"2Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-spine1178","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1016\/S0022-3476(87)80153-1","volume":"110","author":"Alagille D","year":"1987","journal-title":"J Pediatr"},{"key":"b2-spine1178","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199702150-00009"},{"key":"b3-spine1178","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1097\/00001665-199607000-00005","volume":"7","author":"Anderson PJ","year":"1996","journal-title":"J Craniofac Surg"},{"key":"b4-spine1178","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1016\/0303-8467(82)90039-7","volume":"84","author":"de Graaf RJ","year":"1982","journal-title":"Clin Neurol Neurosurg"},{"key":"b5-spine1178","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1111\/jon19966156","volume":"6","author":"Delgado A","year":"1996","journal-title":"J Neuroimaging"},{"key":"b6-spine1178","first-page":"282","volume":"76","author":"Ehrenhaft JL","year":"1943","journal-title":"Surg Gynecol Obstet"},{"key":"b7-spine1178","first-page":"695","volume":"27","author":"Fischer F","year":"1945","journal-title":"J Bone Joint Surg"},{"key":"b8-spine1178","first-page":"407","volume":"17","author":"Lawson ME","year":"1997","journal-title":"J Perinatol"},{"key":"b9-spine1178","first-page":"157","volume":"149","author":"M\u00fcller F","year":"1986","journal-title":"J Anat"},{"key":"b10-spine1178","first-page":"3","volume-title":"The Pediatric Spine: Principles and Practice","author":"Ogden JA","year":"1994"},{"key":"b11-spine1178","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e31818ad3e1"},{"key":"b12-spine1178","doi-asserted-by":"crossref","first-page":"167","DOI":"10.1016\/0899-7071(89)90103-4","volume":"13","author":"Schlitt M","year":"1989","journal-title":"Clin Imaging"},{"key":"b13-spine1178","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1002\/(SICI)1097-0223(199702)17:2<161::AID-PD1>3.0.CO;2-8","volume":"17","author":"Sepulveda W","year":"1997","journal-title":"Prenat Diagn"},{"key":"b14-spine1178","doi-asserted-by":"crossref","first-page":"206","DOI":"10.1016\/S0899-7071(01)00266-2","volume":"25","author":"Sonel B","year":"2001","journal-title":"Clin Imaging"},{"issue":"152","key":"b15-spine1178","first-page":"211","author":"Tsou PM","year":"1980","journal-title":"Clin Orthop Relat Res"}],"container-title":["Journal of Neurosurgery: Spine"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/15\/5\/article-p567.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/j-neurosurg-spine\/15\/5\/article-p567.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,8,29]],"date-time":"2020-08-29T01:54:31Z","timestamp":1598666071000},"score":1,"resource":{"primary":{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/15\/5\/article-p567.xml"}},"subtitle":["Case report"],"short-title":[],"issued":{"date-parts":[[2011,11]]},"references-count":15,"journal-issue":{"issue":"5"},"URL":"https:\/\/doi.org\/10.3171\/2011.6.spine1178","relation":{},"ISSN":["1547-5654"],"issn-type":[{"value":"1547-5654","type":"print"}],"subject":[],"published":{"date-parts":[[2011,11]]}}}
