On magnetic resonance imaging, a spinal cord lesion was present at the ninth thoracic vertebra. The lesion was hyperintense on T2-weighted images (T2-W), and a hyperintense rim was present on T1-weighted postcontrast images. Histologic examination showed a cystic mass lined by squamous epithelial cells. Histopathologic diagnosis was an intramedullary epidermoid spinal cyst. Epidermoid cyst should be a differential diagnosis in young dogs with a myelopathy and an intramedullary spinal cord lesion on magnetic resonance imaging examination.<\/jats:p>","DOI":"10.5326\/jaaha-ms-5583","type":"journal-article","created":{"date-parts":[[2011,11,4]],"date-time":"2011-11-04T12:29:53Z","timestamp":1320409793000},"page":"e145-e149","source":"Crossref","is-referenced-by-count":11,"title":["Intramedullary Epidermoid Cyst in the Thoracic Spine of a Dog"],"prefix":"10.5326","volume":"47","author":[{"given":"Lisa","family":"Lipitz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Rylander","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie E.","family":"Pinkerton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3280","reference":[{"key":"bib1","series-title":"Veterinary neuropathology","first-page":"354","article-title":"Tumors of the central nervous system","author":"Summers","year":"1995","unstructured":"Summers\n              BA\n            , CummingsJF, de LahuntaA.
