High resolution CT scan in pontine ataxic hemiparesis.

Pontine hemorrhage presenting as ataxic hemiparesis.

THE CLINICAL PICTURE of hypertensive pontine hemorrhage is felt to be uniform. Coma is of abrupt onset with pupillary miosis, total external ophthalmoplegia, and quadriplegia. Death is the rule and occurs within hours to days. 2 This picture has been somewhat modified since the advent of CT scanning. Case reports have documented "submassive" pontine hemorrhage with partial to complete recovery....

Ataxic hemiparesis in patients with primary pontine hemorrhage.

Two patients with small primary pontine hemorrhage developed a syndrome identical to ataxic hemiparesis, one 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.

Capsular hypesthetic ataxic hemiparesis.

Twenty-three patients with hypesthetic ataxic hemiparesis underwent computed tomography or magnetic resonance imaging. Twenty-two patients had infarcts of lacunar or slightly larger size in the contralateral posterior limb of the internal capsule. In 15 patients the infarct extended superiorly into the adjacent paraventricular region, and in seven it extended into the lateral thalmus. In eight ...

Thalamic lesion producing ataxic hemiparesis.

Dr. Lamy that such rates are probably a much better reflection of current risk. These studies do not specify the rates for the subgroup with relevant carotid lesions, however, making the problem of rinding appropriate "historical controls" even more vexing. Fortunately, it appears that definitive resolution will become available in the next few years, when several large European and North Ameri...
