We report two cases of vertigo considered to be premonitory symptom of subsequent cerebellar infarction.<BR>Two patients who suffered from vertigo visited our clinics. At that time, they had no obvious neurological symptom except vertigo, hearing loss and tinnitus. They showed spontaneous nystagmus which seemed to be caused by a peripheral vestibular disorder. After one or two weeks, they showed cerebellar signs and CT scan revealed infarctions of cerebellar peduncles. For the diagnosis of premonitory vertigo, we emphasize the importance of detection of background pathology, such as hypertension, arteriosclerosis, diabetes mellitus, hyperlipemia and collagen disease.<BR>Antiplatelet drugs are considered useful in preventing the subsequent infarction. However, we could not prevent the infarctions by the administrations of ticlopidine in either of the present cases.
