Neurologic deficits included a short-strided choppy gait in the thoracic limbs and a long-strided proprioceptive ataxia in the pelvic limbs. Withdrawal reflexes were decreased bilaterally in the thoracic limbs. Signs were consistent with a myelopathy of the caudal cervical\/cranial thoracic spinal cord (i.e., the sixth cervical [C] vertebra to the second thoracic [T] vertebra). A mass associated with the C6\u2013C7 articular facet on the left side was identified on MRI of the cervical spinal cord. The lesion was hyperintense to spinal cord parenchyma on T2-weighted images, hypointense on T1-weighted images, and there was strong homogenous contrast enhancement. Significant spinal cord compression was associated with the lesion. The mass was removed through a C6\u2013C7 dorsal laminectomy and facetectomy. Histopathology of the mass was consistent with a synovial myxoma of the articular facet. A postoperative MRI showed complete surgical resection. Albeit rare, synovial myxomas should be included in the list of differential diagnoses for neoplasms affecting the vertebral columns in dogs.<\/jats:p>","DOI":"10.5326\/jaaha-ms-5992","type":"journal-article","created":{"date-parts":[[2014,3,22]],"date-time":"2014-03-22T01:21:38Z","timestamp":1395451298000},"page":"198-202","source":"Crossref","is-referenced-by-count":7,"title":["Synovial Myxoma in the Vertebral Column of a Dog: MRI Description and Surgical Removal"],"prefix":"10.5326","volume":"50","author":[{"given":"Casey P.","family":"Neary","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William W.","family":"Bush","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deena M.","family":"Tiches","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy C.","family":"Durham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick R.","family":"Gavin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3280","reference":[{"key":"bib1","series-title":"Tumors in domestic animals","first-page":"118","article-title":"Tumors and tumor-like lesions of joints and adjacent soft tissues","author":"Pool","year":"1990","unstructured":"Pool\n              RJ\n            \n          .
