Magnetic resonance findings of meningoencephalitis in a dog seroreactive to Ehrlichia canis in United Kingdom

Abstract

AbstractWe describe a novel clinical presentation and imaging findings in a dog seropositive to Ehrlichia canis. A dog presented with an acute non‐ambulatory tetraparesis and severe obtundation. MRI findings showed multifocal intra‐axial changes centered in the grey matter. The lesions caused mild mass effect and leptomeningeal contrast enhancement. The dog responded to treatment with the progressive reduction of antibody titers detected on the indirect fluorescent antibody test and complete resolution of the clinical signs. Canine monocytic ehrlichiosis should be considered a differential in dogs with thrombocytopenia and meningoencephalitis.
