Capsular ataxic hemiparesis
V. J. Iragui and C. B. McCutchen
Left hemiparesis and left-sided ataxia developed in a 67-year-old man.
Computed tomography (CT) showed an area of decreased attenuation in the
anterior part of the rostral posterior limb of the right internal capsule
that enhanced with contrast. As the patient's condition improved, the
contrast enhancement resolved. The clinical course combined with the
changes in CT scans indicates that the responsible lesion was an infarct.
This report suggests that ataxic hemiparesis can result from an infarct of
the posterior limb of the internal capsule.
