Because they are so rare, their exact origin and details of the clinical manifestations are still unknown. The authors report on five men treated for discal cysts. The mean age of the patients at the time of the surgery was 32 years (range 25\u201338 years). All patients suffered from lower-extremity pain and the results of the straight leg\u2013raising test were positive in all cases. Three patients reported motor weakness and four had sensory disturbance\u2014symptoms similar to those found in patients with lumbar disc herniation. Magnetic resonance imaging demonstrated spherically shaped extradural lesions of various sizes with low and high signal intensities on T<jats:sub>1<\/jats:sub>- and T<jats:sub>2<\/jats:sub>-weighted images, respectively. Discography revealed obvious communication between the cyst and the intervertebral disc with reproducible leg pain in all patients. All patients underwent posterior decompression and excision of the cysts either with or without additional discectomy. The radicular symptoms were remarkably improved in all patients immediately after surgery, and no recurrent lesions were noted during follow up.<\/jats:p>","DOI":"10.3171\/spi.2007.6.1.17","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T12:23:22Z","timestamp":1201177402000},"page":"85-89","source":"Crossref","is-referenced-by-count":108,"title":["Discal cysts of the lumbar spine"],"prefix":"10.3171","volume":"6","author":[{"given":"Masaharu","family":"Nabeta","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hisashi","family":"Yoshimoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigenobu","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiko","family":"Hyakumachi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Yanagibashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Masuda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Eniwa Hospital, Kogane-cho, Eniwa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0060085","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1984.60.3.0617"},{"key":"b2-0060085","first-page":"398","volume":"9","author":"Abrahams JJ","year":"1988","journal-title":"AJNR Am J Neuroradiol"},{"key":"b3-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199405000-00019"},{"key":"b4-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200110010-00014"},{"key":"b5-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00024720-200210000-00015"},{"key":"b6-0060085","doi-asserted-by":"publisher","DOI":"10.1007\/s003300100888"},{"key":"b7-0060085","doi-asserted-by":"crossref","first-page":"369","DOI":"10.1302\/0301-620X.68B3.3733797","volume":"68","author":"Gibson MJ","year":"1986","journal-title":"J Bone Joint Surg Br"},{"key":"b8-0060085","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.145.2.7134440"},{"key":"b9-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199504000-00028"},{"key":"b10-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199501000-00015"},{"key":"b11-0060085","doi-asserted-by":"publisher","DOI":"10.1007\/s004020050323"},{"key":"b12-0060085","doi-asserted-by":"publisher","DOI":"10.1016\/S1529-9430(02)00445-X"},{"key":"b13-0060085","doi-asserted-by":"publisher","DOI":"10.1007\/s002340050584"},{"key":"b14-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200306010-00028"},{"key":"b15-0060085","first-page":"1373","volume":"20","author":"Kono K","year":"1999","journal-title":"AJNR Am J Neuroradiol"},{"key":"b16-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199211000-00030"},{"key":"b17-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-198804000-00004"},{"key":"b18-0060085","doi-asserted-by":"publisher","DOI":"10.1007\/BF01578256"},{"key":"b19-0060085","doi-asserted-by":"publisher","DOI":"10.1016\/S1529-9430(03)00148-7"},{"key":"b20-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199701010-00017"},{"key":"b21-0060085","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199310000-00008"}],"container-title":["Journal of Neurosurgery: Spine"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/6\/1\/article-p85.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/j-neurosurg-spine\/6\/1\/article-p85.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,29]],"date-time":"2021-05-29T00:26:46Z","timestamp":1622248006000},"score":1,"resource":{"primary":{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg-spine\/6\/1\/article-p85.xml"}},"subtitle":["Report of five cases"],"short-title":[],"issued":{"date-parts":[[2007,1]]},"references-count":21,"aliases":["10.3171\/spi.2007.6.1.4","10.3171\/spi.2007.6.1.85"],"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.3171\/spi.2007.6.1.17","relation":{},"ISSN":["1547-5654"],"issn-type":[{"value":"1547-5654","type":"print"}],"subject":[],"published":{"date-parts":[[2007,1]]}}}
