Late onset and rapid progression of cerebellar abiotrophy in a domestic shorthair cat.
A two-year-old male domestic shorthair cat was seen because of sudden onset of incoordination and tremors that had rapidly worsened over five days. Neurological examination revealed severe cerebellar ataxia, intention tremors and bilaterally decreased menace response. Blood work evaluation included a complete cell blood count (CBC), serum biochemistry profile, urinalysis, faecal flotation, cerebrospinal fluid (CSF) analysis and retroviral testing. Except for testing positive for feline immunodeficiency virus (FIV) antibodies, all other results were within the normal range. The patient was euthanased two days later because of progression of clinical signs, and a necropsy was performed. Histologically, lesions were limited to the cerebellum and consistent with cerebellar abiotrophy. No secondary diseases that could explain the rapid development of clinical signs were found. It was considered unlikely that cerebellar degeneration was related to FIV positivity, as virus invasion of the central nervous system (CNS) is mainly limited to the cerebral cortex. This case report is the first to describe late onset and rapid progression cerebellar abiotrophy in a cat.
