Discomfort was suspected upon lateral flexion of the neck. Two magnetic resonance imaging (MRI) examinations at a 3-week interval revealed an intramedullary fluid-filled cavitary lesion adjacent to C7, containing a blood clot.<\/jats:p>\nTreatment and Outcome<\/jats:bold>\u2014Following unsuccessful initial conservative management, surgical marsupialization of the lesion was performed through a dorsal laminectomy, durotomy, and myelotomy at C6 and C7. Histologic evaluation including immunohistochemistry was diagnostic for a vascular anomaly. Initially, the dog was nonambulatory with tetraparesis and became tetraplegic after surgery; movement was regained 6 days later. Four weeks after the procedure, the dog was able to walk unassisted. One year after surgery, the dog was actively running and jumping, with mild residual ataxia in the pelvic limbs.<\/jats:p>\nClinical Relevance<\/jats:bold>\u2014The intramedullary vascular anomaly in this dog was successfully treated with a surgical marsupialization technique. The combination of MRI, histologic eval-uation, and immunohistochemistry enabled lesion localization, evaluation of cavity content, and final diagnosis.<\/jats:p>","DOI":"10.2460\/javma.232.3.399","type":"journal-article","created":{"date-parts":[[2008,2,1]],"date-time":"2008-02-01T20:41:02Z","timestamp":1201898462000},"page":"399-404","source":"Crossref","is-referenced-by-count":10,"title":["Magnetic resonance imaging and marsupialization of a hemorrhagic intramedullary vascular anomaly in the cervical portion of the spinal cord of a dog"],"prefix":"10.2460","volume":"232","author":[{"given":"Kate","family":"Alexander","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louis","family":"Huneault","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Foster","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc-Andr\u00e9","family":"d'Anjou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"Veterinary neuropathology","first-page":"68","article-title":"Malformations of the central nervous system","author":"Summers","year":"1995"},{"key":"ref2","series-title":"Veterinary neuropathology","first-page":"351","article-title":"Tumors of the central nervous system","author":"Summers","year":"1995"},{"key":"ref3","series-title":"J Small Anim Pract","first-page":"439","article-title":"Partial surgical removal of an intramedullary epidermoid cyst from the spinal cord of a dog","volume":"40","author":"Shamir","year":"1999"},{"key":"ref4","series-title":"J Comp Pathol","first-page":"71","article-title":"Arteriovenous malformation of the cervical spinal cord in a dog","volume":"121","author":"Hayashida","year":"1999"},{"key":"ref5","series-title":"J Am Vet Med Assoc","first-page":"1225","article-title":"Acquired syringomyelia in a dog","volume":"201","author":"Cauzinille","year":"1992"},{"key":"ref6","series-title":"J Am Vet Med Assoc","first-page":"1435","article-title":"Intraspinal epidermoid cyst in a dog","volume":"193","author":"Tomlinson","year":"1988"},{"key":"ref7","series-title":"Curr Probl Diagn Radiol","first-page":"79","article-title":"Magnetic resonance imaging of intraspinal cystic lesions: a pictorial review","volume":"31","author":"Evans","year":"2002"},{"key":"ref8","series-title":"Neurosurgery","first-page":"97","article-title":"Spinal neurenteric cysts in the magnetic resonance imaging era","volume":"58","author":"Menezes","year":"2006"},{"key":"ref9","series-title":"Neuroradiology","first-page":"961","article-title":"MR imaging in intramedullary cysticercosis","volume":"43","author":"Parmar","year":"2001"},{"issue":"suppl 1","key":"ref10","series-title":"J Neurosurg","first-page":"104","article-title":"Intramedullary arachnoid cyst.
