The right ear and eyelid both droop.

The bull is ataxic with predominantly right sided proprioceptive deficits.

A sample of cerebrospinal fluid (CSF) taken at the lumbosacral space has normal color, no turbidity but has an increased mononuclear cell count and an elevated protein concentration.

Which one of the following choices is the most likely diagnosis?

Value
