Long-Term Immunosuppressive Therapy with Cyclosporine plus Prednisolone of Necrotizing Meningoencephalitis in a Pekingese Dog

Abstract

A 4-year-old intact female Pekingese dog was presented with ataxia and seizure episodes. Based on magnetic resonance imaging and cerebrospinal fluid analysis results, meningoencephalitis of unknown etiology was suspected. The present case was survived for 1,096 days under cyclosporine plus prednisolone therapy and definitely diagnosed to necrotizing meningoencephalitis. This report describes the clinical findings, serial magnetic resonance imaging characteristics, and pathologic features of a necrotizing meningoencephalitis and long-term survival after cyclosporine with prednisolone therapy.
