Abstract

One and a half syndrome is an ipsilateral gaze paresis or palsy combined with and internuclear ophthalmoplegia on contralateral gaze. The lesion site is at the paramedian pontine reticular formation and the adjacent MLF. The common causes are unilateral pontine infarction and multiple sclerosis. We experienced a case of one and a half syndrome which has a suspected small pontine infarct.
