末梢性めまいと鑑別困難であった小脳梗塞例

We experienced a case of cerebellar infarction with vertigo. A 39-year-old male complained of vertigo and a slight headache. There was no significant nystagmus or cranial sign on the first day. CT was also normal. After two days, he was admitted to the hospital because his consciousness became unclear. At that time, CT and MRI showed cerebellar infarction involving the postero-inferior cerebellar artery. His consciousness became clear and he showed almost no impairment after treatment. Angiography revealed dissection of the vertebral artery. The clinical signs of cerebellar infarction are occasionally similar to those of inner ear disorders. In such cases, neurological and neuro-otological examinations are important in distinguishing cerebellar infarction from inner ear diseases.
