Crossed Ataxia A
Background and Purpose—Ever since the seminal description of ataxic hemiparesis contralateral to a pontine lesion by Miller-Fisher, the question of why contralesional crossing pontocerebellar fibers do not more frequently produce ipsilesional hemiataxia was raised. The few cases of “quadrataxic hemiparesis” or bilateral leg ataxia remain exceptions. Summary of Case—We report an even more unusua...
متن کاملCrossed optic ataxia: possible role of the dorsal splenium.
An unusual combination of disconnective syndromes is reported: transcortical motor aphasia, left arm apraxia and optic ataxia. Neuropathological examination showed a left parieto-occipital and a subcortical frontal infarct and a lesion of the dorsal part of the posterior two-fifths of the callosum. The frontal lesion caused the transcortical motor aphasia and produced the left arm apraxia. Visu...
متن کاملHomolateral ataxia and crural paresis: a crossed cerebral-cerebellar diaschisis.
A patient developed weakness of the right leg and homolateral ataxia of the arm, caused by a subcortical infarct in the area supplied by the anterior cerebral artery in the left paracentral region, demonstrated by CT and MRI. Cerebral blood flow studied by technetium-labelled hexamethyl-propylene-amine oxime using single photon emission computed tomography showed decreased blood flow in the lef...
