Summary 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.
