Palatal Myoclonus Associated with Cerebral Cysticercosis

ABSTRACT

A case of palatal myoclonus associated with cerebral cysticercosis is reported. The patient, a 54-year-old man, presented with clicking sound in the left ear for 2 years duration. Cerebral cysticercosis was con-firmed by pathologic diagnosis and CSF specific IgG antibody test. The brain CT disclosed multiple intraparenchymal punctate calcifications including left dentate nucleus. All of these findings indicate that one of the basic pathophysiologic mechanisms of palatal myoconus is the defect of ipsilateral dentate nucleus and this lesion can be evoked by the cysticercosis.
