title: Computed tomographic findings of ceroid lipofuscinosis in a dog.
abstract: A two-year and seven-month-old, castrated male border collie was presented for a two-month history of progressive neurological signs including blindness, ataxia, dementia, and partial seizures. A complete blood count, serum biochemical profile, urinalysis, thoracic radiographs, and cerebrospinal fluid analysis were within reference ranges. Computed tomography (CT) of the brain showed dilatation of the ventricles and atrophy of the cerebral cortex. A central nervous system (CNS) storage disease was suspected, and the dog was euthanized due to a poor prognosis. Light and electron microscopic examination revealed neuronal degeneration with pigment accumulation in neurons of the CNS, in ganglia of the peripheral nervous system, and in several non-nervous tissues. Ceroid lipofuscinosis was diagnosed based on the microscopic and ultrastructural lesions detected. This is the second report of CT findings in a canine clinical patient with ceroid lipofuscinosis.
