Unusual neuro-ophthalmologic findings in a patient with anti-Yo-associated cerebellar degeneration

Abstract

We report a woman with anti-Yo-associated cerebellar degeneration, severe eye movement abnormalities, and no evidence of malignancy after 3 years of extensive evaluation. The prominent neuro-ophthalmologic findings suggest brainstem involvement, which may be a novel manifestation of anti-Yo associated paraneoplastic syndrome.
