Abstract:
A rare case, 49 year old man, of cerebellar infarction with occurrence of the sudden deafness was reported. On the otoneurological examination, hearing test and calroric test showed deafness and 19% vestibular hypofunction on the right side respectively. Mild vertigo was noticed, but spontaneous nystagmus was not observed. Cerebellar function test was intact. Magnetic resonance imaging (MRI) showed the acute cerebellar infarction in the area of the anterior inferior cerebellar artery (AICA) on the right side. After 7 days heparinization treatment, hearing threshold was much improved. An early recovery of hearing loss may be attributable to the recanalized circulation disturbance or the developement of collateral circulation.
