title: Hemifacial spasm and cerebellopontine angle epidermoid: case report and review.
abstract: A case with hemifacial spasm with tinnitus due to right cerebellopontine angle epidermoid is reported. The tumour was supposed to have caused the displacement of the part of anterior inferior cerebellar artery in the vicinity of the root exit zone of the ipsilateral facial nerve. Near total removal of the tumour along with microvascular decompression was done and the patient was completely relieved of his symptoms. The incidence of hemifacial spasm due to cerebellopontine angle epidermoid is extremely low. The cause of such an association is discussed and relevant literature is reviewed.
