Ataxic hemiparesis in patients with primary pontine hemorrhage.

Abstract
Patients (2) with small primary pontine hemorrhage developed a syndrome identical to ataxic hemiparesis, 1 of the lacunar syndromes of Fisher. The possible mechanisms of the homolateral cerebellar signs, pyramidal signs and dysarthria are discussed. Lesions of the ipsilateral pontine nuclei may be responsible for the homolateral ataxia.
