Acute blindness in a dog with Acinetobacter-associatedpostencephalitic hydrocephalus

[摘要] A 10-month-old male Welsh Corgi with a history of acute blindness underwentneuro-ophthalmological testing and magnetic resonance imaging (MRI). Vision testingrevealed complete visual deficits but the electroretinograph and pupillary light reflexwere normal in both eyes. The motor and sensory functions of the eyelids and eyes werealso normal. The MRI revealed compression of the optic chiasm caused by severeventriculomegaly in the lateral and third ventricles. Such lesions are associated withinflammatory stenotic lesions in the mesencephalic aqueduct. Moderate neutrophilicpleocytosis was observed during cerebrospinal fluid analysis and Acinetobacterlwoffii was isolated, leading to a diagnosis ofAcinetobacter-positive obstructive hydrocephalus. This is the firstreported case of culture-proven Acinetobacter-associated postencephalitichydrocephalus with acute blindness in a dog.
