Ataxic hemiparesis from lesions of the corona radiata.

Ipsilateral cerebellar and pyramidal signs suddenly developed in three patients. Computed tomography revealed small infarcts of the corona radiata in two patients and a small infarct in the posterior limb of the internal capsule in the third. Ataxic hemiparesis can result from lesions of the corona radiata as well as many other points along the corticopontine pathways.
