An Unusual Cause of Hemifacial Spasm
Journal Title: Chettinad Health City Medical Journal - Year 2017, Vol 6, Issue 1
Abstract
Hemifacial spasm is a hyperactive rhizopathy of the seventh cranial nerve. It is usually ascribed to vascular compression of the facial nerve at the root exit zone. Tumors, vascular malformations are unusual causes of hemifacial spasms. We report one young adult presenting with hemifacial spasms as a sole manifestation. On imaging it was found to be having large cerebellopontine angle epidermoid cyst and was managed surgically.He had good relief of hemifacial spasms after surgery. Hemifacial spasms as a sole presentation of cerebellopontine angle epidermoid cyst is relatively rare. Only few cases are reported in the literature.Patients with hemifacial spasms should have imaging to exclude structural causes at the cerebellopontine angle and brainstem.
