Two patients with tremor caused by cortical lesions.
Myoclonic tremor due to cortical lesions is a rare condition and must be distinguished from other causes of tremor. This is because the treatment strategies of tremor may differ due to the various etiologies. We present here two cases with myoclonic tremor caused by parietal cortical lesions showing tremulous finger movement provoked by action and posture. Clinical and electrophysiological features of the patients were reported and compared with the features of the patients with cortical tremor in association with cortical reflex myoclonus. Both of our patients responded well to anticonvulsants such as valproate and clonazepam. In patients with acute postural tremor, cortical lesions such as mass occupying lesions, ischemic lesions and arteriovenous malformations should be taken into consideration.
