Palatal tremor (PT) is frequently caused by brainstem lesions. The inferior olive plays a major role in the pathophysiologic mechanisms involved. We report a case of PT of cortical origin presenting as epilepsia partialis continua. EEG showed continuous left frontocentral epileptiform discharges and both single photon emission computed tomography (SPECT) and positron emission tomography (PET) showed focal hypoperfusion and hypometabolism in the corresponding location.
腭部震颤（PT）常由脑干病变引起。下橄榄核在相关病理生理机制中起主要作用。我们报告一例起源于皮质的PT，表现为持续性部分性癫痫。脑电图显示左侧额中央区持续性癫痫样放电，单光子发射计算机断层扫描（SPECT）和正电子发射断层扫描（PET）均显示相应部位局灶性灌注减低和代谢减低。
