Abstract:
A 17-year-old male presented with paroxysmal kinesigenic choreoathetosis (PKC) associated with frontotemporal arachnoid cyst. Xenon-133 single photon emission computed tomography detected a slight but equivocal decrease in regional cerebral blood flow in the vicinity of basal ganglia associated with the PKC episodes. PKC continued after surgical removal of the cyst but was well controlled by oral administration of carbamazepine. Whether the pathogenesis of symptomatic PKC was associated with the cortical lesion could not be determined in the present case.
