A male, 8-mo-old, Japanese Black calf with a history of secondary dystocia as a result of fetal gigantism had lameness and gait disturbance. At autopsy, multifocal dural thickening with adhesions to the adjacent spinal cord was observed at T12\u201313 and L4\u20135 vertebral levels. Microscopically, numerous traumatic neuroma-like fascicles of nerve twigs were embedded in the dura mater with abundant collagenous connective tissue. By immunohistochemistry, axons and Schwann cells were confirmed in each nerve fascicle. Our observations suggest that avulsion injuries in the preganglionic fibers of the spinal nerve roots, and secondary spinal cord compression, resulted in the development of neurologic signs.<\/jats:p>","DOI":"10.1177\/1040638720957640","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T07:27:43Z","timestamp":1600154863000},"page":"968-971","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Calving-related intradural avulsion injuries of the thoracolumbar spinal nerve roots in a calf"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0882-4165","authenticated-orcid":false,"given":"Hayate","family":"Nishiura","sequence":"first","affiliation":[{"name":"Laboratories of Veterinary Pathology, Co-department of Veterinary Medicine, Iwate University, Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shino","family":"Jou","sequence":"additional","affiliation":[{"name":"Laboratories of Veterinary Pathology, Co-department of Veterinary Medicine, Iwate University, Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Ogata","sequence":"additional","affiliation":[{"name":"NOSAI Iwate (Iwate prefectural branch of Japan\u2019s Agricultural Insurance Scheme), Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Kondo","sequence":"additional","affiliation":[{"name":"NOSAI Iwate (Iwate prefectural branch of Japan\u2019s Agricultural Insurance Scheme), Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiro","family":"Ichijo","sequence":"additional","affiliation":[{"name":"Farm Animal Internal Medicine, Co-department of Veterinary Medicine, Iwate University, Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Laboratories of Veterinary Pathology, Co-department of Veterinary Medicine, Iwate University, Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Ochiai","sequence":"additional","affiliation":[{"name":"Laboratories of Veterinary Pathology, Co-department of Veterinary Medicine, Iwate University, Morioka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,9,15]]},"reference":[{"key":"bibr1-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1186\/s13028-019-0479-8"},{"key":"bibr2-1040638720957640","first-page":"153","volume-title":"Veterinary Neuroanatomy and Clinical Neurology","author":"de Lahunta A","year":"2015","edition":"4"},{"key":"bibr3-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-39055-2.00013-9"},{"key":"bibr4-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5288(92)90045-4"},{"key":"bibr5-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1177\/030098589002700110"},{"key":"bibr6-1040638720957640","first-page":"228","volume-title":"Blackwell\u2019s Five-Minute Veterinary Consult: Ruminant","author":"Haskell SRR","year":"2008"},{"key":"bibr7-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1920.01110010098007"},{"key":"bibr8-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.11-0485"},{"key":"bibr9-1040638720957640","doi-asserted-by":"publisher","DOI":"10.4236\/ojas.2011.12006"},{"key":"bibr10-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1136\/vetreco-2017-000254"},{"key":"bibr11-1040638720957640","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcpa.2016.05.003"},{"key":"bibr12-1040638720957640","first-page":"830","volume":"29","author":"Schuh JACL","year":"1988","journal-title":"Can Vet J"},{"key":"bibr13-1040638720957640","unstructured":"Scott P.
