Description 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 40-yo-woman with anti-Yo antibody associated with ovarian cancer. Initial symptoms 2.5 years prior (to this video) included imbalance and dysarthria. She complained of oscillopsia which was due to her upbeat nystagmus (presumably the result of brainstem involvement), and diplopia (she had an esotropia greater at distance which is common with cerebellar pathology). There were also intermittent spontaneous saccadic intrusions, hypermetric saccades, choppy smooth pursuit and VOR suppression - ocular motor abnormalities that are commonly seen with posterior fossa disease. At the time when the video was taken (2.5 years after symptom onset), severe brainstem and cerebellar atrophy was apparent on MRI.

She complained of oscillopsia due to spontaneous upbeat nystagmus (presumably the result of brainstem involvement), and on examination, she had intermittent saccadic intrusions, hypermetric saccades (in all planes), saccadic smooth pursuit and vestibulo-ocular reflex suppression. MRI demonstrated severe brainstem and cerebellar atrophy. https://collections.lib.utah.edu/ark:/87278/s6bz9v92
