抄録

A 34-year-old female with positional vertigo and nystagmus had been misdiagnosed as having benign paroxysmal positional vertigo because of the positional nystagmus with latent period and decrescence and the absence of hearing loss and of neurological symptoms during attacks of vertigo. However, MRI and CT-scans showed a cerebellar cavernous angioma. MRI and CT-scan are necessary in the diagnosis of the cause of vertigo even when it seems to be due to peripheral vestibular disease.
