The MRI findings included multifocal, asymmetric forebrain lesions affecting both the gray and white matter, an area suggestive of focal necrosis, and loss of corticomedullary distinction. A midline shift and caudal transtentorial herniation were noted, suggestive of greater than normal intracranial pressure.<\/jats:p>\n<jats:p><jats:bold>Treatment and Outcome<\/jats:bold>\u2014Because the dog's clinical signs worsened despite medical treatment and additional evidence of increased intracranial pressure, bilateral craniectomy and durectomy were performed. Histologic evaluation of a brain biopsy specimen revealed bilateral and asymmetric areas of necrosis in the subcortical white matter and adjacent gray matter. At the periphery of the necrotic areas, there was increased expression of glial fibrillary acidic protein and Virchow-Robin spaces were expanded by CD3+ lymphocytes. Results of immunohistochemical analysis of brain tissue were negative for canine distemper virus, <jats:italic>Neospora canis<\/jats:italic>, and <jats:italic>Toxoplasma gondii.<\/jats:italic> These clinical, imaging, and histopathologic findings were compatible with necrotizing meningoencephalitis. The dog's neurologic status continued to worsen following surgery. Repeated MRI revealed ongoing signs of increased intracranial pressure, despite the bilateral craniectomy. The owners elected euthanasia.<\/jats:p>\n<jats:p><jats:bold>Clinical Relevance<\/jats:bold>\u2014To the author's knowledge, this is the first report of necrotizing meningoencephalitis in a large mixed-breed dog. Necrotizing meningoencephalitis should be considered as a differential diagnosis in dogs other than small or toy breeds that have signs suggestive of inflammatory disease.<\/jats:p>","DOI":"10.2460\/javma.245.11.1274","type":"journal-article","created":{"date-parts":[[2014,11,19]],"date-time":"2014-11-19T14:54:29Z","timestamp":1416408869000},"page":"1274-1278","source":"Crossref","is-referenced-by-count":5,"title":["Necrotizing
