Using magnetic resonance imaging,we studied 6 patients with the dysarthria-clumsy hand syndrome.All were found to have pontine infarctions contralateral to the symptomatic side.Clinically,these patients exhibited dysarthria;"clumsiness",characterized by dysmetria,dysrhythmia, dysdiadochokinesia and sometimes truncal and gait ataxia;and mild ipsilateral weakness.Previous clinical-anatomical correlations for this syndrome are limited by inconsistencies in clinical diagnostic criteria and low-resolution imaging methods.In our patients,and in a review of the literature,the overwhelming majority of patients with the dysarthria- clumsy hand syndrome had pontine infarcts.We conclude that if rigid clinical criteria were used,the label of the dysarthria-clumsy hand syndrome predicts a lesion in the contralateral basis pontis. |
