Five patients with cerebellar infarction consulted one of us (Otolaryngologist) at an early stage of the disease. Dizziness or gait disturbance was the chief complaint in four of the five. Cerebellar signs were seen in three, but only for a short period. Muscular weakness and unequal tendon reflexes were noted in only two patients and hypesthesia in one. Thus, symptoms were similar to those of patients with inner ear lesions. Neuro-otologic examination revealed bilateral gaze nystagmus in all five patients for one to two weeks. Positional and paroxysmal nystagmus tests showed down beat nystagmus in two patients and apogeotropic direction changing positional nystagmus in two. No hearing disturbance occurred in any of them. Brain CT examination should be performed if any of the above-mentioned signs are present in dizzy patients.
