Head flutter

A previously healthy 30-year-old man presented with oscillopsia, involuntary head movements, and imbalance. His examination showed intermittent ocular flutter (OF), bursts of back-to-back horizontal head movements time-locked with OF (head flutter) (figure; video at Neurology.org), and generalized ataxia. Head MRI, paraneoplastic antibody testing, CSF analysis, toxicology and serology panel, and CT of chest/abdomen/pelvis were unrevealing. The patient fully recovered after 6 months with monthly IV immunoglobulin.
