We report a 57-year-old woman with progressive gait disturbance, headache, character change, con-vulsion and coma.

She was well until 55 years of age, when she noted an onset of unsteady gait. At times she experienced transient weakness in her right hand, which was followed some difficulty in articulation. She was admitted to our service for the work up on April 6, 1992. Neurologic examination at that time revealed an alert Japanese lady in no acute distress. She was oriented to all spheres, however, she was somewhat bradyphrenic and had some disturbance in recent memory.
