title: [Study of cerebellar infarction with isolated vertigo].
abstract: Isolated vertigo is generally attributed to labyrinthine disease, but may also signal otherwise asymptomatic cerebellar infarction. Of 309 subjects admitted between April 2004 and March 2009 for the single symptom of acute vertigo initially thought to be labyrinthine, four were found to have cerebellar infarction of the posterior inferior cerebellar artery area (PICA). All were over 60 years old and had risk factors including hypertension, diabetes mellitus, arrhythmia, and/or hyperlipidemia. Two had trunk ataxia, with magnetic resonance imaging (MRI) showing infarction within a few days. The other two could walk without apparent trunk ataxia, however, it took 4 to 7 days to find the infarction, mainly through neurological, neurootological, and MRI findings. Neurologically, astasia, dysbasia or trunk ataxia were important signs. Neurootologically, nystagmus and electronystagmographic testing involving eye tracking, saccade, and optokinetic patttens were useful.
