Abstract
We report a 24-year old woman who developed bilateral hemifacial spasm alternating from one side to the other. The spasms followed a left peripheral facial palsy 2 years previously. This unusual type of bilateral hemifacial spasm was possibly due to lesions of multiple sclerosis in the brainstem.
