title: Enterogenous cyst as a rare cause of hemifacial spasm.
abstract: Hemifacial spasm (HFS) is most frequently caused by vascular compression of the facial nerve at the root exit zone of the brain stem, but there are other rare causes. An enterogenous cyst (EC) is a rare congenital lesion which occurs rarely in the cerebellopontine angle. The authors report a patient with HFS from an EC and review unusual causes of HFS.
