Facial myokymia--a false localizing sign in obstructive communicating hydrocephalus. A case report.
Facial myokymia was evident in a 57-year-old man exhibiting both clinical and radiological signs of obstructive communicating hydrocephalus. Insertion of a ventriculoatrial shunt resulted in resolution of clinical symptomatology including the facial myokymia. Since there was no evidence of a structural brain stem pathology, it is believed that in this case, facial myokymia represented a false localizing sign secondary to obstructive communication hydrocephalus.
